I am now using blogger to built my own adsense blog. But I still can't understand how to add adsense code into RSS feeds or atom feeds? Please help me. Thanks.
You can't add Adsense into your feeds because it is currently invite-only and Google is not accepting anymore applications. https://www.google.com/support/adsense/bin/answer.py?answer=20012&topic=957
@Xitanto: you can try but I don't think the ads would show up. Google would see the ad request as coming from an RSS/Atom XML feed and just not serve it. I would think that Google would be smart enough to close that little loophole from the get go.
sending adsense code in an email is a breach of google contract, does this also applys on RSS/ATOM feeds?
I don't think so, because the user has control on whether or not they use that feed - just like whether or not a user visits a site.
