Recently I visited the AdSense for feeds blog of google & I found that now it even easier to configure their blogs to work with FeedBurner and AdSense for Feeds, with just a few clicks, are able to do both at the same time.
To set this up, go to Blogger and select the blog you wish to monetize on your Blogger Dashboard, and select “Monetize.” This will give you some basic options for configuring ads, and if you already have connected your Blogger feed to FeedBurner, will confirm that the proper feed is being configured. AdSense for feeds will automatically pick the right ad sizes for your users, content, and end medium.
After setup, you will be able to view your AdSense reports (including feed revenue) directly from the Blogger Dashboard, as well as from your AdSense account. Additional feed management options for your feed and feed analytics will be available from http://feedburner.google.com.
