Google announced today the launch of AdSense for Feeds in beta. PPC advertisers can now have their ads placed in RSS/Atom syndicated content feeds, and content publishers can earn revenue from placing these PPC ads in their feeds.

Until now, syndicated feeds have been a largely ad-less frontier. It will be interesting to observe how readers react to seeing ads in their favourite feeds, and if they respond with the torrent of clicks that publishers and Google are hoping for. 

Google has published a document outlining best practices for incorporating AdSense for Feeds into your feeds, and are now accepting applications from publishers who would like to participate in the beta program.
