This document compares search advertising and social advertising. Search advertising involves placing ads on search engine results pages, targeted to specific keywords. Social advertising places ads on social media platforms like Facebook. The document notes that search advertising for non-branded keywords can cost $6-8, but directing those ads to Facebook can increase the cost to over $13. In contrast, social ads on Facebook targeting specific demographics can cost as little as $0.50. Overall, the document argues that social advertising is more cost-effective and allows targeting audiences in ways that search advertising does not.
