An update on Google's feature-phone crawling & indexing

Wednesday, November 30, 2016

Limited mobile devices, "feature-phones", require a special form of markup or a transcoder for web content. Most websites don't provide feature-phone-compatible content in WAP/WML any more. Given these developments, we've made changes in how we crawl feature-phone content (note: these changes don't affect smartphone content):

1. We've retired the feature-phone Googlebot

We won't be using the feature-phone user-agents for crawling for search going forward.

2. Use "handheld" link annotations for dynamic serving of feature-phone content.

Some sites provide content for feature-phones through dynamic serving, based on the user's user-agent. To understand this configuration, make sure your desktop and smartphone pages have a self-referential alternate URL link for handheld (feature-phone) devices:

<link rel="alternate" media="handheld" href="[current page URL]" />

This is a change from our previous guidance of only using the "vary: user-agent" HTTP header. We've updated our documentation on making feature-phone pages accordingly. We hope adding this link element is possible on your side, and thank you for your help in this regard. We'll continue to show feature-phone URLs in search when we can recognize them, and when they're appropriate for users.

3. We're retiring feature-phone tools in Search Console

Without the feature-phone Googlebot, special sitemaps extensions for feature-phone, the Fetch as Google feature-phone options, and feature-phone crawl errors are no longer needed. We continue to support sitemaps and other sitemaps extensions (such as for videos or Google News), as well as the other Fetch as Google options in Search Console.

We've worked to make these changes as minimal as possible. Most websites don't serve feature-phone content, and wouldn't be affected. If your site has been providing feature-phone content, we thank you for your help in bringing the Internet to feature-phone users worldwide!

For any questions, feel free to drop by our Webmaster Help Forums!

Building Indexable Progressive Web Apps

Wednesday, November 09, 2016

Progressive Web Apps (PWAs) are taking advantage of new technologies to bring the best of mobile sites and native applications to users -- and they’re one of the most exciting new ideas on the web. But to truly have an impact, it's important that they’re indexable and linkable. Every recommendation presented in this article is an existing best practice for indexability -- regardless of whether you're building a Progressive Web App or a simple static website. Nonetheless, we have collated these best practices to provide a checklist to guide you:

Make Your Content CrawlableWhy? Historically, websites would always generate or render their HTML on the server which is the simplest way to ensure your content is directly linkable. Web applications popularised the concept of client-side rendering in which content is updated dynamically on the page as the users navigates without requiring the page to be reloaded.The modern approach is hybrid rendering, in which server-side rendering is used when a user navigates directly to a URL and client-side rendering is used after the initial page load for subsequent navigation and asynchronous requests.Our server-side PWA sample demonstrates pure server-side rendering, while our hybrid PWA sample demonstrates the combined approach.If you are unfamiliar with the server-side and client-side rendering terminology, check out these articles on the web read here and here. .boxbox { width: 100%; word-wrap:break-word; padding: 0.2em; } .badbox { background-color: #eba; } .goodbox { background-color: #ded; } .avoidbox { background-color: #ffd; } .boxbox h5 { font-size: 1em; font-weight: bold; margin: 0;} .boxbox p { margin-top: 0.6em; margin-bottom: 0.6em; } br.endboxen { clear: both; } h3.subhead { margin-top: 2em; }

Best Practice:

Use server-side or hybrid rendering so users receive the content in the initial payload of their web request.

Always ensure your URLs are independently accessible:

https://www.example.com/product/25/

The above should deep link to that particular resource.

If you can’t support server-side or hybrid rendering for your Progressive Web App and you decide to use client-side rendering, we recommend using the Google Search Console “Fetch as Google tool” to verify your content successfully renders for our search crawler.

Don’t:

Don't redirect users accessing deep links back to your web app's homepage.

Additionally, serving an error page to users instead of deep linking should also be avoided.

Provide Clean URLsWhy? Fragment identifiers (#user/24601/ or #!user/24601/) were an effective workaround for browsers to AJAX new content from a server without reloading the page. This design is known as client-side rendering.However, the fragment identifier syntax isn’t compatible with some web tools, frameworks and protocols such as Facebook’s Open Graph protocol.The History API enables us to update the URL without fragment identifiers while still fetching resources asynchronously and therefore avoiding page reloads -- it’s the best of both worlds. The AJAX crawling scheme (with its #! / escaped-fragment URLs) made sense at its time, but is now no longer recommended. Our hybrid PWA and client-side PWA samples demonstrate the History API.

Best Practice:

Provide clean URLs without fragment identifiers (# or #!) such as:

https://www.example.com/product/25/

If using client-side or hybrid rendering be sure to support browser navigation with the History API.

Avoid:

Using the #! URL structure to drive unique URLs is discouraged:

https://www.example.com/#!product/25/

It was introduced as a workaround before the advent of the History API. It is considered a separate pattern to the purely # URL structure.

Don’t:

Using the # URL structure without the accompanying ! symbol is unsupported:

https://www.example.com/#product/25/

This URL structure is already a concept in the web and relates to deep linking into content on a particular page.

Specify Canonical URLsWhy? The best way to eliminate confusion for indexing when the same content is available under multiple URLs (be it the same or different domains) is to mark one page as the canonical, and all other pages that duplicate that content to refer to it.

Best Practice:

Include the following tag across all pages mirroring a particular piece of content:

<link rel="canonical" href="https://www.example.com/your-url/" />

If you are supporting Accelerated Mobile Pages be sure to correctly use its counterpart rel=”amphtml” instruction as well.

Avoid:

Avoid purposely duplicating content across multiple URLs and not using the rel="canonical" link element.

For example, the rel="canonical" link element can reduce ambiguity for URLs with tracking parameters.

Don’t:

Avoid creating conflicting canonical references between your pages.

Design for Multiple DevicesWhy? It’s important that all your users get the best experience possible when viewing your website, regardless of their device. Make your site responsive in its design -- fonts, margins, paddings, buttons and general design of your site should scale dynamically based on screen resolutions and device viewports. Small images scaled up for desktop or tablet devices give a poor experience. Conversely, super high resolution images take a long time to download on mobile phones and may impact mobile scroll performance.Read more UX for PWAs here.

Best Practice:

Use “srcset” attribute to fetch different resolution images for different density screens to avoid downloading images larger than the device’s screen is capable of displaying.

Scale your font size and line height to ensure your text is legible no matter the size of the device. Similarly ensure the padding and margins of elements also scale sensibly.

Test various screen resolutions using the Chrome Developer Tool’s Device Mode feature and Mobile Friendly Test tool.

Don’t:

Don't show different content to users than you show to Google. If you use redirects or user agent detection (a.k.a. browser sniffing or dynamic serving) to alter the design of your site for different devices it’s important that the content itself remains the same.

Use the Search Console “Fetch as Google” tool to verify the content fetched by Google matches the content a user sees.

For usability reasons, avoid using fixed-size fonts.

Develop IterativelyWhy? One of the safest paths to take when adding features to a web application is to make changes iteratively. If you add features one at a time you can observe the impact of each individual change.Alternatively many developers prefer to view their progressive web application as an opportunity to overhaul their mobile site in one fell swoop -- developing the new web app in an isolated environment and swapping it with their existing mobile site once ready.When developing features iteratively try to break the changes into separate pieces. For example, if you intend to move from server-side rendering to hybrid rendering then tackle that as a single iteration -- rather than in combination with other features.Both approaches have their own pros and cons. Iterating reduces the complexity of dealing with search indexability as the transition is continuous. However, iterating might result in a slower development process and potentially a less innovative overhaul if development is not starting from scratch.In either case, the most sensitive areas to keep an eye on are your canonical URLs and your site’s robots.txt configuration.

Best Practice:

Iterate on your website incrementally by adding new features piece by piece.

For example, if don’t support HTTPS yet then start by migrating to a secure site.

Avoid:

If you’ve developed your progressive web app in an isolated environment, then avoid launching it without checking the rel-canonical links and robots.txt are setup appropriately.

Ensure your rel-canonical links point to the real site and that your robots.txt configuration allows crawlers to crawl your new site.

Don’t:

It’s logical to prevent crawlers from indexing your in-development site before launch but don’t forget to unblock crawlers from accessing your new site when you launch.

Use Progressive EnhancementWhy? Wherever possible it’s important to detect browser features before using them. Feature detection is also better than testing for browsers that you believe support a given feature.A common bad practice in the past was to enable or disable features by testing which browser the user had. However, as browsers are constantly evolving with features this technique is strongly discouraged.Service Worker is a relatively new technology and it’s important to not break compatibility in the pursuit of progress -- it's a perfect example of when to use progressive enhancement.

Best Practice:

Before registering a Service Worker check for the availability of its API:

if ('serviceWorker' in navigator) {
...

Use per API detection method for all your website’s features.

Don’t:

Never use the browser’s user agent to enable or disable features in your web app. Always check whether the feature’s API is available and gracefully degrade if unavailable.

Avoid updating or launching your site without testing across multiple browsers! Check your site analytics to learn which browsers are most popular among your user base.

Test with Search ConsoleWhy? It’s important to understand how Google Search views your site’s content. You can use Search Console to fetch individual URLs from your site and see how Google Search views them using the “Crawl > Fetch as Google“ feature. Search Console will process your JavaScript and render the page when that option is selected; otherwise only the raw HTML response is shown Google Search Console also analyses the content on your page in a variety of ways including detecting the presence of Structured Data, Rich Cards, Sitelinks & Accelerated Mobile Pages.

Best Practice:

Monitor your site using Search Console and explore its features including “Fetch as Google”.

Provide a Sitemap via Search Console “Crawl > Sitemaps” It can be an effective way to ensure Google Search is aware of all your site’s pages.

Annotate with Schema.org structured dataWhy? Schema.org structured data is a flexible vocabulary for summarizing the most important parts of your page as machine-processable data. This can be as general as simply saying that a page is a NewsArticle, or as specific as detailing the location, band name, venue and ticket vendor for a touring band, or summarizing the ingredients and steps for a recipe.The use of this metadata may not make sense for every page on your web application but it’s recommended where it’s sensible. Google extracts it after the page is rendered.There are a variety of data types including “NewsArticle”, “Recipe” & “Product” to name a few. Explore all the supported data types here.

Best Practice:

Verify that your Schema.org meta data is correct using Google’s Structured Data Testing Tool.

Check that the data you provided is appearing and there are no errors present.

Don’t:

Avoid using a data type that doesn’t match your page’s actual content. For example don’t use “Recipe” for a T-Shirt you’re selling -- use “Product” instead.

Annotate with Open Graph & Twitter CardsWhy? In addition to the Schema.org metadata it can be helpful to add support for Facebook’s Open Graph protocol and Twitter rich cards as well.These metadata formats improve the user experience when your content is shared on their corresponding social networks.If your existing site or web application utilises these formats it’s important to ensure they are included in your progressive web application as well for optimal virality.

Best Practice:

Test your Open Graph markup with the Facebook Object Debugger Tool.

Familiarise yourself with Twitter’s metadata format.

Don’t:

Don’t forget to include these formats if your existing site supports them.

Test with Multiple BrowsersWhy? Clearly from a user perspective it’s important that a website behaviors the same across all browsers. While the experience might adapt for different screen sizes we all expect a mobile site to work the same on similarly sized devices whether it’s an iPhone or an Android mobile phone.While the web can be perceived as fragmented due to number of browsers in use around the world, this variety and competition is part of what makes the web such an innovative platform. Thankfully, web standards have never been more mature than they are now and modern tools enable developers to build rich, cross browser compatible websites with confidence.

Best Practice:

Use cross browser testing tools such as BrowserStack.com, Browserling.com or BrowserShots.org to ensure your PWA is cross browser compatible.

Measure Page Load PerformanceWhy? The faster a website loads for a user the better their user experience will be. Optimizing for page speed is already a well known focus in web development but sometimes when developing a new version of a site the necessary optimizations are not considered a high priority.When developing a progressive web application we recommend measuring the performance of your page load speed and optimizing before launching the site for the best results.

Best Practice:

Use tools such as Page Speed Insights and Web Page Test to measure the page load performance of your site. While Googlebot has a bit more patience in rendering, research has shown that 40% of consumers will leave a page that takes longer than three seconds to load..

Read more about our web page performance recommendations and the critical rendering path here.

Don’t:

Avoid leaving optimization as a post-launch step. If your website’s content loads quickly before migrating to a new progressive web application then it’s important to not regress in your optimizations.

We hope that the above checklist is useful and provides the right guidance to help you develop your Progressive Web Applications with indexability in mind. As you get started, be sure to check out our Progressive Web App indexability samples that demonstrate server-side, client-side and hybrid rendering.

Deprecating our AJAX crawling scheme

Wednesday, October 14, 2015

tl;dr: We are no longer recommending the AJAX crawling proposal we made back in 2009.

In 2009, we made a proposal to make AJAX pages crawlable. Back then, our systems were not able to render and understand pages that use JavaScript to present content to users. Because "crawlers … [were] not able to see any content … created dynamically," we proposed a set of practices that webmasters can follow in order to ensure that their AJAX-based applications are indexed by search engines.

Times have changed. Today, as long as you're not blocking Googlebot from crawling your JavaScript or CSS files, we are generally able to render and understand your web pages like modern browsers. To reflect this improvement, we recently updated our technical Webmaster Guidelines to recommend against disallowing Googlebot from crawling your site's CSS or JS files.

Since the assumptions for our 2009 proposal are no longer valid, we recommend following the principles of progressive enhancement. For example, you can use the History API pushState() to ensure accessibility for a wider range of browsers (and our systems).

Questions and answers

Q: My site currently follows your recommendation and supports _escaped_fragment_. Would my site stop getting indexed now that you've deprecated your recommendation?
A: No, the site would still be indexed. In general, however, we recommend you implement industry best practices when you're making the next update for your site. Instead of the _escaped_fragment_ URLs, we'll generally crawl, render, and index the #! URLs.

Q: Is moving away from the AJAX crawling proposal to industry best practices considered a site move? Do I need to implement redirects?
A: If your current setup is working fine, you should not have to immediately change anything. If you're building a new site or restructuring an already existing site, simply avoid introducing _escaped_fragment_ urls. .

Q: I use a JavaScript framework and my webserver serves a pre-rendered page. Is that still ok?
A: In general, websites shouldn't pre-render pages only for Google -- we expect that you might pre-render pages for performance benefits for users and that you would follow progressive enhancement guidelines. If you pre-render pages, make sure that the content served to Googlebot matches the user's experience, both how it looks and how it interacts. Serving Googlebot different content than a normal user would see is considered cloaking, and would be against our Webmaster Guidelines.

Deprecation of the old Webmaster Tools API

Thursday, March 12, 2015

Last fall we announced the new Webmaster Tools API, which helps you to automate a number of important aspects using code. With the pending shutdown of ClientLogin, we're going to turn down the old Webmaster Tools API on April 20, 2015. If you're still using the old API, getting started with the new one is fairly easy. The new API covers everything from the old version except for messages and keywords. We have examples in Python, Java, as well as OACurl (for command-line fans & quick testing). Additionally, there's the Site Verification API to add sites programmatically to your account. The Python search query data download will continue to be available for the moment, and replaced by an API in the upcoming quarters. As always, should you have any questions, feel free to comment here, or post in our Webmaster Help Forum. Posted by John Mueller, fan of command lines & APIs, Google Zuerich

Finding more mobile-friendly search results

Thursday, February 26, 2015

Webmaster level: allWhen it comes to search on mobile devices, users should get the most relevant and timely results, no matter if the information lives on mobile-friendly web pages or apps. As more people use mobile devices to access the internet, our algorithms have to adapt to these usage patterns. In the past, we’ve made updates to ensure a site is configured properly and viewable on modern devices. We’ve made it easier for users to find mobile-friendly web pages and we’ve introduced App Indexing to surface useful content from apps. Today, we’re announcing two important changes to help users discover more mobile-friendly content: 1. More mobile-friendly websites in search resultsStarting April 21, we will be expanding our use of mobile-friendliness as a ranking signal. This change will affect mobile searches in all languages worldwide and will have a significant impact in our search results. Consequently, users will find it easier to get relevant, high quality search results that are optimized for their devices. To get help with making a mobile-friendly site, check out our guide to mobile-friendly sites. If you’re a webmaster, you can get ready for this change by using the following tools to see how Googlebot views your pages:

If you want to test a few pages, you can use the Mobile-Friendly Test.

If you have a site, you can use your Webmaster Tools account to get a full list of mobile usability issues across your site using the Mobile Usability Report.

2. More relevant app content in search resultsStarting today, we will begin to use information from indexed apps as a factor in ranking for signed-in users who have the app installed. As a result, we may now surface content from indexed apps more prominently in search. To find out how to implement App Indexing, which allows us to surface this information in search results, have a look at our step-by-step guide on the developer site. If you have questions about either mobile-friendly websites or app indexing, we’re always happy to chat in our Webmaster Help Forum.Posted by Takaki Makino, Chaesang Jung, and Doantam Phan

Case Studies: Fixing Hacked Sites

Wednesday, February 18, 2015

Webmaster Level: AllEvery day, thousands of websites get hacked. Hacked sites can harm users by serving malicious software, collecting personal information, or redirecting them to sites they didn't intend to visit. Webmasters want to fix hacked sites quickly, but unfortunately recovering from a hack can be a complicated process.We're trying to make the process of recovering from a hack easier for webmasters with features like Security Issues, Help for Hacked Sites, and a section of our forum just for hacked sites. Recently we talked to two webmasters with hacked sites to learn more about how they were able to fix their sites. We're sharing their stories with the hope that they might provide ideas to other webmasters who have been victims of hacking. We're also using these stories and other feedback for improving our documentation for hacked sites to make the process easier for everyone going forward.Case Study #1: Restaurant website with multiple hack-injected scriptsA restaurant website using Wordpress received a message from Google in their Webmaster Tools account, alerting them that their site had been altered by hackers. To protect Google users, the website was labelled as hacked in Google's search results. The webmaster of the site, Sam, looked at the source code and noticed many unfamiliar links on the site with pharmaceuticals terms such as "viagra" and "cialis." She also noticed many pages where the meta description tags (in the HTML) had added content such as "buy valtrex in florida." There were also hidden div tags (also in the HTML) of many pages that linked to many sites. None of these links were added by Sam. Sam removed all of the hacked content she found and filed a reconsideration request. The request was rejected but in the message she received from Google, she was advised to check for any unfamiliar scripts in the any PHP files (or any other server files), as well as changes to the .htaccess file. These files are likely to have scripts added by the hackers that modify the site. These scripts typically only show the hacked content to search engines, while hiding the content from a normal user. Sam checked out all of the .php files and compared them to the clean copies she had in her backup. She found new content added to her footer.php, index.php, and functions.php. When she replaced those files with the clean backups, she could no longer find any hacked content on her site. When she filed another reconsideration request, she got a response from Google notifying her that her site was free from hacked content!Even though Sam had cleaned up the hacked content on her site, she knew that she would need to continue to secure her site against future attacks. She followed the steps below to keep her site safe in the future:

Keep the CMS (content management system like WordPress, Joomla, Drupal, etc) up to date with the most current version. Make sure plugins are up to date as well.

Make sure the account used to access the administrative features of the CMS uses a difficult and unique password.

If the CMS supports it, enable 2-step verification for login. (This might also be called two factor authentication or two step authentication.) This is recommended for the account being used for password recovery as well. Most email providers, like Google, Microsoft, Yahoo all support this!

Make sure the plugins and themes installed are from a reputable source - pirated plugins or themes can often contain code that makes it even easier for hackers to get in!

Case Study #2: Professional website with lots of hard to find hacked pages A small business owner named Maria who also manages her own website received a message in her Webmaster Tools that her site was hacked. The message provided an example of a page added by hackers: http://example.com/where-to-buy-cialis-over-the-counter/. She talked to her hosting provider who looked at the source code on the homepage but could not find any pharmaceutical keywords. When the hosting provider visited http://example.com/where-to-buy-cialis-over-the-counter/, it returned an error page. Maria also bought a malware scanning service but the service was not able to find any malicious content on her site.Maria then went to Webmaster Tools and used the Fetch as Google tool on the example URL Google had provided (http://example.com/where-to-buy-cialis-over-the-counter/) which returned no content. Confused, she filed a reconsideration request and received a rejection message which advised her to do two things:

Verify the non-www version of her site as hackers often try to hide content in folders that may be overlooked by the webmaster.

While it may seem like http://example.com and http://www.example.com are the same site, Google actually treats these as different sites. http://example.com is referred to as the "root domain" while http://www.example.com is called the subdomain. Maria had http://www.example.com verified but not http://example.com verified which is important because the pages added by hackers were non-www pages like http://example.com/where-to-buy-cialis-over-the-counter/. Once she verified http://example.com she was able to successfully see the hacked content on the provided URL with the Fetch as Google tool in Webmaster Tools.

Check her .htaccess file for new rules.

Maria talked to her hosting provider who showed her how to access her .htaccess file. She noticed right away that her .htaccess file had some strange content that she had not added:

<IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{HTTP_USER_AGENT} (google|yahoo|msn|aol|bing) [OR] RewriteCond %{HTTP_REFERER} (google|yahoo|msn|aol|bing) RewriteRule ^([^/]*)/$ /main.php?p=$1 [L] </IfModule>

The mod_rewrite rule you see above was inserted by the hacker and redirects anyone coming from certain search engines, as well as search engine crawlers, to main.php, which generates all of the hacked content. It's also possible that these rules can redirect users accessing the site on a mobile device. On the same day, she also saw that a recent malware scan found suspicious content on the main.php file. One top of that, she also noticed an unknown user in the ftp users area of her website development software.

She removed the main.php file, the .htaccess file, and removed the unknown user from her FTP users area and her site was no longer hacked!Steps to prevent getting hacked in the future

Avoid using FTP when transferring files to your servers. FTP does not encrypt any traffic, including passwords. Instead, use SFTP, which will encrypt everything, including your password, as a protection against eavesdroppers examining network traffic.

Check the permissions on sensitive files like .htaccess. Your hosting provider may be able to assist you if you need help. The .htaccess file can be used to improve and protect your site, but it can also be used for malicious hacks if they are able to gain access to it.

Be vigilant and look for new and unfamiliar users in your administrative panel and any other place where there may be users that can modify your site.

We hope your site never gets hacked, but if it does, we have many resources for hacked webmasters on our Help for Hacked Sites page. If you need more help or would like to share your own tips, you can post in our Webmaster Help Forum. If you do post to the forum or submit a reconsideration request for your site, please include #NoHacked.Posted by Julian Prentice and Yuan Niu, Search Quality Team

Google Public DNS and Location-Sensitive DNS Responses

Monday, December 15, 2014

Webmaster level: advancedRecently the Google Public DNS team, in collaboration with Akamai, reached an important milestone: Google Public DNS now propagates client location information to Akamai nameservers. This effort significantly improves the accuracy of approximately 30% of the location-sensitive DNS responses returned by Google Public DNS. In other words, client requests to Akamai hosted content can be routed to closer servers with lower latency and greater data transfer throughput. Overall, Google Public DNS resolvers serve 400 billion responses per day and more than 50% of them are location-sensitive.DNS is often used by Content Distribution Networks (CDNs) such as Akamai to achieve location-based load balancing by constructing responses based on clients’ IP addresses. However, CDNs usually see the DNS resolvers’ IP address instead of the actual clients’ and are therefore forced to assume that the resolvers are close to the clients. Unfortunately, the assumption is not always true. Many resolvers, especially those open to the Internet at large, are not deployed at every single local network.To solve this issue, a group of DNS and content providers, including Google, proposed an approach to allow resolvers to forward the client’s subnet to CDN nameservers in an extension field in the DNS request. The subnet is a portion of the client’s IP address, truncated to preserve privacy. The approach is officially named edns-client-subnet or ECS.This solution requires that both resolvers and CDNs adopt the new DNS extension. Google Public DNS resolvers automatically probe to discover ECS-aware nameservers and have observed the footprint of ECS support from CDNs expanding steadily over the past years. By now, more than 4000 nameservers from approximately 300 content providers support ECS. The Google-Akamai collaboration marks a significant milestone in our ongoing efforts to ensure DNS contributes to keeping the Internet fast. We encourage more CDNs to join us by supporting the ECS option.For more information about Google Public DNS, please visit our website. For CDN operators, please also visit “A Faster Internet” for more technical details.Posted by Yunhong Gu, Tech Lead, Google Public DNS

The four steps to appiness

Tuesday, December 09, 2014

Webmaster Level: intermediate to advanced

App deep links are the new kid on the block in organic search, and they’re picking up speed faster than you can say “schema.org ViewAction”! For signed-in users, 15% of Google searches on Android now return deep links to apps through App Indexing. And over just the past quarter, we've seen the number of clicks on app deep links jump by 10x.

We’ve gotten a lot of feedback from developers and seen a lot of implementations gone right and others that were good learning experiences since we opened up App Indexing back in June. We’d like to share with you four key steps to monitor app performance and drive user engagement:

1. Give your app developer access to Webmaster Tools

App indexing is a team effort between you (as a webmaster) and your app development team. We show information in Webmaster Tools that is key for your app developers to do their job well. Here’s what’s available right now:

Errors in indexed pages within apps
Weekly clicks and impressions from app deep link via Google search
Stats on your sitemap (if that’s how you implemented the app deep links)

...and we plan to add a lot more in the coming months!

We’ve noticed that very few developers have access to Webmaster Tools. So if you want your app development team to get all of the information they need to fix app-related issues, it’s essential for them to have access to Webmaster Tools.

Any verified site owner can add a new user. Pick restricted or full permissions, depending on the level of access you’d like to give:

2. Understand how your app is doing in search results

How are users engaging with your app from search results? We’ve introduced two new ways for you to track performance for your app deep links:

We now send a weekly clicks and impressions update to the Message center in your Webmaster Tools account.
You can now track how much traffic app deep links drive to your app using referrer information - specifically, the referrer extra in the ACTION_VIEW intent. We're working to integrate this information with Google Analytics for even easier access. Learn how to track referrer information on our Developer site.

3. Make sure key app resources can be crawled

Blocked resources are one of the top reasons for the “content mismatch” errors you see in Webmaster Tools’ Crawl Errors report. We need access to all the resources necessary to render your app page. This allows us to assess whether your associated web page has the same content as your app page.

To help you find and fix these issues, we now show you the specific resources we can’t access that are critical for rendering your app page. If you see a content mismatch error for your app, look out for the list of blocked resources in “Step 5” of the details dialog:

4. Watch out for Android App errors

To help you identify errors when indexing your app, we’ll send you messages for all app errors we detect, and will also display most of them in the “Android apps” tab of the Crawl errors report.

In addition to the currently available “Content mismatch” and “Intent URI not supported” error alerts, we’re introducing three new error types:

APK not found: we can’t find the package corresponding to the app.
No first-click free: the link to your app does not lead directly to the content, but requires login to access.
Back button violation: after following the link to your app, the back button did not return to search results.

In our experience, the majority of errors are usually caused by a general setting in your app (e.g. a blocked resource, or a region picker that pops up when the user tries to open the app from search). Taking care of that generally resolves it for all involved URIs.

Good luck in the pursuit of appiness! As always, if you have questions, feel free to drop by our Webmaster help forum.

Are you a robot? Introducing “No CAPTCHA reCAPTCHA”

Wednesday, December 03, 2014

reCAPTCHA protects the websites you love from spam and abuse. So, when you go online—say, for some last-minute holiday shopping—you won't be competing with robots and abusive scripts to access sites. For years, we’ve prompted users to confirm they aren’t robots by asking them to read distorted text and type it into a box, like this:

But, we figured it would be easier to just directly ask our users whether or not they are robots—so, we did! We’ve begun rolling out a new API that radically simplifies the reCAPTCHA experience. We’re calling it the “No CAPTCHA reCAPTCHA” and this is how it looks:

On websites using this new API, a significant number of users will be able to securely and easily verify they’re human without actually having to solve a CAPTCHA. Instead, with just a single click, they’ll confirm they are not a robot.

A brief history of CAPTCHAs

While the new reCAPTCHA API may sound simple, there is a high degree of sophistication behind that modest checkbox. CAPTCHAs have long relied on the inability of robots to solve distorted text. However, our research recently showed that today’s Artificial Intelligence technology can solve even the most difficult variant of distorted text at 99.8% accuracy. Thus distorted text, on its own, is no longer a dependable test.

To counter this, last year we developed an Advanced Risk Analysis backend for reCAPTCHA that actively considers a user’s entire engagement with the CAPTCHA—before, during, and after—to determine whether that user is a human. This enables us to rely less on typing distorted text and, in turn, offer a better experience for users. We talked about this in our Valentine’s Day post earlier this year.

The new API is the next step in this steady evolution. Now, humans can just check the box and in most cases, they’re through the challenge.

Are you sure you’re not a robot?

However, CAPTCHAs aren't going away just yet. In cases when the risk analysis engine can't confidently predict whether a user is a human or an abusive agent, it will prompt a CAPTCHA to elicit more cues, increasing the number of security checkpoints to confirm the user is valid.

Making reCAPTCHAs mobile-friendly

This new API also lets us experiment with new types of challenges that are easier for us humans to use, particularly on mobile devices. In the example below, you can see a CAPTCHA based on a classic Computer Vision problem of image labeling. In this version of the CAPTCHA challenge, you’re asked to select all of the images that correspond with the clue. It's much easier to tap photos of cats or turkeys than to tediously type a line of distorted text on your phone.

Adopting the new API on your site

As more websites adopt the new API, more people will see "No CAPTCHA reCAPTCHAs". Early adopters, like Snapchat, WordPress, Humble Bundle, and several others are already seeing great results with this new API. For example, in the last week, more than 60% of WordPress’ traffic and more than 80% of Humble Bundle’s traffic on reCAPTCHA encountered the No CAPTCHA experience—users got to these sites faster. To adopt the new reCAPTCHA for your website, visit our site to learn more.

Humans, we'll continue our work to keep the Internet safe and easy to use. Abusive bots and scripts, it’ll only get worse—sorry we’re (still) not sorry.

Tracking mobile usability in Webmaster Tools

Wednesday, October 29, 2014

Webmaster Level: intermediateMobile is growing at a fantastic pace - in usage, not just in screen size. To keep you informed of issues mobile users might be seeing across your website, we've added the Mobile Usability feature to Webmaster Tools. The new feature shows mobile usability issues we’ve identified across your website, complete with graphs over time so that you see the progress that you've made. A mobile-friendly site is one that you can easily read & use on a smartphone, by only having to scroll up or down. Swiping left/right to search for content, zooming to read text and use UI elements, or not being able to see the content at all make a site harder to use for users on mobile phones. To help, the Mobile Usability reports show the following issues: Flash content, missing viewport (a critical meta-tag for mobile pages), tiny fonts, fixed-width viewports, content not sized to viewport, and clickable links/buttons too close to each other.

We strongly recommend you take a look at these issues in Webmaster Tools, and think about how they might be resolved; sometimes it's just a matter of tweaking your site's template! More information on how to make a great mobile-friendly website can be found in our Web Fundamentals website (with more information to come soon).If you have any questions, feel free to join us in our webmaster help forums (on your phone too)!Posted by John Mueller, Webmaster Trends Analyst, Zurich

Best practices for XML sitemaps & RSS/Atom feeds

Thursday, October 16, 2014

Webmaster level: intermediate-advancedSubmitting sitemaps can be an important part of optimizing websites. Sitemaps enable search engines to discover all pages on a site and to download them quickly when they change. This blog post explains which fields in sitemaps are important, when to use XML sitemaps and RSS/Atom feeds, and how to optimize them for Google.Sitemaps and feedsSitemaps can be in XML sitemap, RSS, or Atom formats. The important difference between these formats is that XML sitemaps describe the whole set of URLs within a site, while RSS/Atom feeds describe recent changes. This has important implications:

XML sitemaps are usually large; RSS/Atom feeds are small, containing only the most recent updates to your site.

XML sitemaps are downloaded less frequently than RSS/Atom feeds.

For optimal crawling, we recommend using both XML sitemaps and RSS/Atom feeds. XML sitemaps will give Google information about all of the pages on your site. RSS/Atom feeds will provide all updates on your site, helping Google to keep your content fresher in its index. Note that submitting sitemaps or feeds does not guarantee the indexing of those URLs.Example of an XML sitemap: <?xml version="1.0" encoding="utf-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<url>
   <loc>http://example.com/mypage</loc>
   <lastmod>2011-06-27T19:34:00+01:00</lastmod>
   
</url>
<url>
   ...
</url>
</urlset> Example of an RSS feed: <?xml version="1.0" encoding="utf-8"?>
<rss>
<channel>
   
   <item>
     
     <link>http://example.com/mypage</link>
     <pubDate>Mon, 27 Jun 2011 19:34:00 +0100</pubDate>
   </item>
   <item>
     ...
   </item>
</channel>
</rss> Example of an Atom feed: <?xml version="1.0" encoding="utf-8"?>
<feed xmlns="http://www.w3.org/2005/Atom">

<entry>
   <link href="http://example.com/mypage" />
   <updated>2011-06-27T19:34:00+01:00</updated>
   
</entry>
<entry>
   ...
</entry>
</feed> “other tags” refer to both optional and required tags by their respective standards. We recommend that you specify the required tags for Atom/RSS as they will help you to appear on other properties that might use these feeds, in addition to Google Search.Best practicesImportant fieldsXML sitemaps and RSS/Atom feeds, in their core, are lists of URLs with metadata attached to them. The two most important pieces of information for Google are the URL itself and its last modification time: URLsURLs in XML sitemaps and RSS/Atom feeds should adhere to the following guidelines:

Only include URLs that can be fetched by Googlebot. A common mistake is including URLs disallowed by robots.txt — which cannot be fetched by Googlebot, or including URLs of pages that don't exist.

Only include canonical URLs. A common mistake is to include URLs of duplicate pages. This increases the load on your server without improving indexing.

Last modification timeSpecify a last modification time for each URL in an XML sitemap and RSS/Atom feed. The last modification time should be the last time the content of the page changed meaningfully. If a change is meant to be visible in the search results, then the last modification time should be the time of this change.

XML sitemap uses <lastmod>

RSS uses <pubDate>

Atom uses <updated>

Be sure to set or update last modification time correctly:

Specify the time in the correct format: W3C Datetime for XML sitemaps, RFC3339 for Atom and RFC822 for RSS.

Only update modification time when the content changed meaningfully.

Don’t set the last modification time to the current time whenever the sitemap or feed is served.

XML sitemapsXML sitemaps should contain URLs of all pages on your site. They are often large and update infrequently. Follow these guidelines:

For a single XML sitemap: update it at least once a day (if your site changes regularly) and ping Google after you update it.

For a set of XML sitemaps: maximize the number of URLs in each XML sitemap. The limit is 50,000 URLs or a maximum size of 10MB uncompressed, whichever is reached first. Ping Google for each updated XML sitemap (or once for the sitemap index, if that's used) every time it is updated. A common mistake is to put only a handful of URLs into each XML sitemap file, which usually makes it harder for Google to download all of these XML sitemaps in a reasonable time.

RSS/AtomRSS/Atom feeds should convey recent updates of your site. They are usually small and updated frequently. For these feeds, we recommend:

When a new page is added or an existing page meaningfully changed, add the URL and the modification time to the feed.

In order for Google to not miss updates, the RSS/Atom feed should have all updates in it since at least the last time Google downloaded it. The best way to achieve this is by using PubSubHubbub. The hub will propagate the content of your feed to all interested parties (RSS readers, search engines, etc.) in the fastest and most efficient way possible.

Generating both XML sitemaps and Atom/RSS feeds is a great way to optimize crawling of a site for Google and other search engines. The key information in these files is the canonical URL and the time of the last modification of pages within the website. Setting these properly, and notifying Google and other search engines through sitemaps pings and PubSubHubbub, will allow your website to be crawled optimally, and represented accordingly in search results.If you have any questions, feel free to post them here, or to join other webmasters in the webmaster help forum section on sitemaps.Posted by Alkis Evlogimenos, Google Feeds Team

An update to the Webmaster Tools API

Thursday, September 11, 2014

Webmaster level: advanced

Over the summer the Webmaster Tools team has been cooking up an update to the Webmaster Tools API. The new API is consistent with other Google APIs, makes it easier to authenticate for apps or web-services, and provides access to some of the main features of Webmaster Tools.

If you've used other Google APIs, getting started with the new Webmaster Tools API will be easy! We have examples for Python, Java, as well as OACurl (for fans of command lines).

This API allows you to:

list, add, or remove sites from your account (you can currently have up to 500 sites in your account)
list, add, or remove sitemaps for your websites
get warning, error, and indexed counts for individual sitemaps
get a time-series of all kinds of crawl errors for your site
list crawl error samples for specific types of errors
mark individual crawl errors as "fixed" (this doesn't change how they're processed, but can help simplify the UI for you)

We'd love to see what you're building with our APIs! Feel free to link to your projects in the comments below. Should you have any questions about the usage of the API, feel free to post in our help forum as well.

Optimizing for Bandwidth on Apache and Nginx

Thursday, September 04, 2014

Webmaster level: advancedEveryone wants to use less bandwidth: hosts want lower bills, mobile users want to stay under their limits, and no one wants to wait for unnecessary bytes. The web is full of opportunities to save bandwidth: pages served without gzip, stylesheets and JavaScript served unminified, and unoptimized images, just to name a few.So why isn't the web already optimized for bandwidth? If these savings are good for everyone then why haven't they been fixed yet? Mostly it's just been too much hassle. Web designers are encouraged to "save for web" when exporting their artwork, but they don't always remember. JavaScript programmers don't like working with minified code because it makes debugging harder. You can set up a custom pipeline that makes sure each of these optimizations is applied to your site every time as part of your development or deployment process, but that's a lot of work.An easy solution for web users is to use an optimizing proxy, like Chrome's. When users opt into this service their HTTP traffic goes via Google's proxy, which optimizes their page loads and cuts bandwidth usage by 50%. While this is great for these users, it's limited to people using Chrome who turn the feature on and it can't optimize HTTPS traffic.With Optimize for Bandwidth, the PageSpeed team is bringing this same technology to webmasters so that everyone can benefit: users of other browsers, secure sites, desktop users, and site owners who want to bring down their outbound traffic bills. Just install the PageSpeed module on your Apache or Nginx server [1], turn on Optimize for Bandwidth in your configuration, and PageSpeed will do the rest.If you later decide you're interested in PageSpeed's more advanced optimizations, from cache extension and inlining to the more aggressive image lazyloading and defer JavaScript, it's just a matter of enabling them in your PageSpeed configuration.Learn more about installing PageSpeed or enabling Optimize for Bandwidth.Posted by Jeff Kaufman, Make the Web Fastopen sourceIISATS

HTTPS as a ranking signal

Wednesday, August 06, 2014

Webmaster level: allSecurity is a top priority for Google. We invest a lot in making sure that our services use industry-leading security, like strong HTTPS encryption by default. That means that people using Search, Gmail and Google Drive, for example, automatically have a secure connection to Google. Beyond our own stuff, we’re also working to make the Internet safer more broadly. A big part of that is making sure that websites people access from Google are secure. For instance, we have created resources to help webmasters prevent and fix security breaches on their sites. We want to go even further. At Google I/O a few months ago, we called for “HTTPS everywhere” on the web. We’ve also seen more and more webmasters adopting HTTPS (also known as HTTP over TLS, or Transport Layer Security), on their website, which is encouraging. For these reasons, over the past few months we’ve been running tests taking into account whether sites use secure, encrypted connections as a signal in our search ranking algorithms. We've seen positive results, so we're starting to use HTTPS as a ranking signal. For now it's only a very lightweight signal — affecting fewer than 1% of global queries, and carrying less weight than other signals such as high-quality content — while we give webmasters time to switch to HTTPS. But over time, we may decide to strengthen it, because we’d like to encourage all website owners to switch from HTTP to HTTPS to keep everyone safe on the web.

In the coming weeks, we’ll publish detailed best practices (it's in our help center now) to make TLS adoption easier, and to avoid common mistakes. Here are some basic tips to get started:

Decide the kind of certificate you need: single, multi-domain, or wildcard certificate

Use 2048-bit key certificates

Use relative URLs for resources that reside on the same secure domain

Use protocol relative URLs for all other domains

Check out our Site move article for more guidelines on how to change your website’s address

Don’t block your HTTPS site from crawling using robots.txt

Allow indexing of your pages by search engines where possible. Avoid the noindex robots meta tag.

If your website is already serving on HTTPS, you can test its security level and configuration with the Qualys Lab tool. If you are concerned about TLS and your site’s performance, have a look at Is TLS fast yet?. And of course, if you have any questions or concerns, please feel free to post in our Webmaster Help Forums.We hope to see more websites using HTTPS in the future.

Introducing the Google News Publisher Center

Monday, August 04, 2014

(Cross-posted on the Google News Blog)

Webmaster level: All

UPDATE: Great News -- The Publisher Center is now available in all countries where Google News has an edition.

If you're a news publisher, your website has probably evolved and changed over time -- just like your stories. But in the past, when you made changes to the structure of your site, we might not have discovered your new content. That meant a lost opportunity for your readers, and for you. Unless you regularly checked Webmaster Tools, you might not even have realized that your new content wasn’t showing up in Google News. To prevent this from happening, we are letting you make changes to our record of your news site using the just launched Google News Publisher Center.

With the Publisher Center, your potential readers can be more informed about the articles they’re clicking on and you benefit from better discovery and classification of your news content. After verifying ownership of your site using Google Webmaster Tools, you can use the Publisher Center to directly make the following changes:

Update your news site details, including changing your site name and labeling your publication with any relevant source labels (e.g., “Blog”, “Satire” or “Opinion”)
Update your section URLs when you change your site structure (e.g., when you add a new section such as http://example.com/2014commonwealthgames or http://example.com/elections2014)
Label your sections with a specific topic (e.g., “Technology” or “Politics”)

Whenever you make changes to your site, we’d recommend also checking our record of it in the Publisher Center and updating it if necessary.

Try it out, or learn more about how to get started.

At the moment the tool is only available to publishers in the U.S. but we plan to introduce it in other countries soon and add more features. In the meantime, we’d love to hear from you about what works well and what doesn’t. Ultimately, our goal is to make this a platform where news publishers and Google News can work together to provide readers with the best, most diverse news on the web.

Testing robots.txt files made easier

Wednesday, July 16, 2014

Webmaster level: intermediate-advancedTo crawl, or not to crawl, that is the robots.txt question.Making and maintaining correct robots.txt files can sometimes be difficult. While most sites have it easy (tip: they often don't even need a robots.txt file!), finding the directives within a large robots.txt file that are or were blocking individual URLs can be quite tricky. To make that easier, we're now announcing an updated robots.txt testing tool in Webmaster Tools.You can find the updated testing tool in Webmaster Tools within the Crawl section:

Here you'll see the current robots.txt file, and can test new URLs to see whether they're disallowed for crawling. To guide your way through complicated directives, it will highlight the specific one that led to the final decision. You can make changes in the file and test those too, you'll just need to upload the new version of the file to your server afterwards to make the changes take effect. Our developers site has more about robots.txt directives and how the files are processed. Additionally, you'll be able to review older versions of your robots.txt file, and see when access issues block us from crawling. For example, if Googlebot sees a 500 server error for the robots.txt file, we'll generally pause further crawling of the website. Since there may be some errors or warnings shown for your existing sites, we recommend double-checking their robots.txt files. You can also combine it with other parts of Webmaster Tools: for example, you might use the updated Fetch as Google tool to render important pages on your website. If any blocked URLs are reported, you can use this robots.txt tester to find the directive that's blocking them, and, of course, then improve that. A common problem we've seen comes from old robots.txt files that block CSS, JavaScript, or mobile content — fixing that is often trivial once you've seen it.We hope this updated tool makes it easier for you to test & maintain the robots.txt file. Should you have any questions, or need help with crafting a good set of directives, feel free to drop by our webmaster's help forum!Posted by Asaph Arnon, Webmaster Tools team

Rendering pages with Fetch as Google

Tuesday, May 27, 2014

Webmaster level: all

The Fetch as Google feature in Webmaster Tools provides webmasters with the results of Googlebot attempting to fetch their pages. The server headers and HTML shown are useful to diagnose technical problems and hacking side-effects, but sometimes make double-checking the response hard: Help! What do all of these codes mean? Is this really the same page as I see it in my browser? Where shall we have lunch? We can't help with that last one, but for the rest, we've recently expanded this tool to also show how Googlebot would be able to render the page.

Viewing the rendered page

In order to render the page, Googlebot will try to find all the external files involved, and fetch them as well. Those files frequently include images, CSS and JavaScript files, as well as other files that might be indirectly embedded through the CSS or JavaScript. These are then used to render a preview image that shows Googlebot's view of the page.

You can find the Fetch as Google feature in the Crawl section of Google Webmaster Tools. After submitting a URL with "Fetch and render," wait for it to be processed (this might take a moment for some pages). Once it's ready, just click on the response row to see the results.

Handling resources blocked by robots.txt

Googlebot follows the robots.txt directives for all files that it fetches. If you are disallowing crawling of some of these files (or if they are embedded from a third-party server that's disallowing Googlebot's crawling of them), we won't be able to show them to you in the rendered view. Similarly, if the server fails to respond or returns errors, then we won't be able to use those either (you can find similar issues in the Crawl Errors section of Webmaster Tools). If we run across either of these issues, we'll show them below the preview image.

We recommend making sure Googlebot can access any embedded resource that meaningfully contributes to your site's visible content, or to its layout. That will make Fetch as Google easier for you to use, and will make it possible for Googlebot to find and index that content as well. Some types of content – such as social media buttons, fonts or website-analytics scripts – tend not to meaningfully contribute to the visible content or layout, and can be left disallowed from crawling. For more information, please see our previous blog post on how Google is working to understand the web better.

We hope this update makes it easier for you to diagnose these kinds of issues, and to discover content that's accidentally blocked from crawling. If you have any comments or questions, let us know here or drop by in the webmaster help forum.

Making your site more mobile-friendly with PageSpeed Insights

Monday, May 19, 2014

Webmaster level: all

To help developers and webmasters make their pages mobile-friendly, we recently updated PageSpeed Insights with additional recommendations on mobile usability.

Poor usability can diminish the benefits of a fast page load. We know the average mobile page takes more than 7 seconds to load, and by using the PageSpeed Insights tool and following its speed recommendations, you can make your page load much faster. But suppose your fast mobile site loads in just 2 seconds instead of 7 seconds. If mobile users still have to spend another 5 seconds once the page loads to pinch-zoom and scroll the screen before they can start reading the text and interacting with the page, then that site isn’t really fast to use after all. PageSpeed Insights’ new User Experience rules can help you find and fix these usability issues.

These new recommendations currently cover the following areas:

These rules are described in more detail in our help pages. When you’re ready, you can test your pages and the improvements you make using the PageSpeed Insights tool. We’ve also updated PageSpeed Insights to use a mobile friendly design, and we’ve translated our documents into additional languages.

As always, if you have any questions or feedback, please post in our discussion group.
