I don't understand how the RSS feeds work with Adsense. Maybe I'm just too thick headed, but so far I haven't seen any ads in the feeds. Huh?
I guess if you have a feed you can add your code and show ads in the feed. Got me, awaiting for more answers.
It just shows adsense adds to ppl who subscibe to your RSS feed that is it. In my experience though it works extremely poorly in terms of making $$. People who subscribe to a RSS feeds HATE to see ads and will just unsubscibe!!
Not because you are not earning and you don't understand the system it means it's not good... Here's the video I created several years ago when adsense just started its feed feature... Please understand my English.. LOL http://www.youtube.com/watch?v=RpURMfrZVwY
Where did you read that? Adsense does recommend using full feeds, but I haven't seen it be a requirement anywhere: https://www.google.com/adsense/support/bin/answer.py?answer=20134
