This document summarizes research on using online advertising networks as an alternative to advertising directly on automotive information sites to reach in-market auto buyers. It presents data from five auto advertising campaigns that showed networks can deliver cost-effective results by starting broadly and optimizing over time. Key findings include:
- The majority of auto site visitors are not ready to purchase within 3 months, and in-market buyers spend less than 1% of online time on these sites.
- Campaigns that optimized placements based on performance outperformed those targeting only automotive categories.
- Categories assumed to reach car buyers, like automotive sites, often underperformed while unexpected categories like careers and money/finance performed best.
