AdSense for Feeds

The emergence of RSS and Atom feeds has created a new way of sharing content with the world. Until now, finding a way to monetize these feeds was a difficult task. Without the need for users to visit the feed site, publishers were gaining eyes but were decreasing ad coverage. The solution arrived with the release of AdSense for feeds, a way of inserting relevant Google ads into RSS and Atom feeds. If you share your content through either of these technologies, check out the AdSense for feeds section of AdSense Support to learn how to earn money from your feed.
