Content marketing is about communicating with customers without direct selling by delivering helpful information. It aims to make customers more knowledgeable rather than pitching products. While content marketing is a recent term, similar approaches have been used for decades like radio programs created by P&G. Today's consumers extensively research purchases online, trusting peer recommendations over ads. Content marketing can differentiate brands by engaging customers who have more media options. Developing an effective content strategy involves understanding the audience, researching their interests, creating relevant content streams, distributing through appropriate channels, and measuring results to refine the approach.
