hi i have seen a option in google adsense "adsense for feeds but don't how to use can any buddy explain how to use it .... Thanks...
login to http://feedburner.google.com. Put your website details, follow the process and you will get the feeds burnt by feedburner. Modify your that website feed to point to the new feed generated by feedburner. Now your adsense for feeds will work. If someone subscribes to your feeds, he will get it via feedburner which will contain google ads. If someone clicks on the ads and if it is a legitimate click you will get paid for the same which will reflect in Adsense for feeds option in Google Adsense account.
