Google has closed down its FeedBurner Ad Network, and is offering publishers its AdSense instead, paidContent reported Wednesday.

Google bought FeedBurner in June 2007 for about US$100 million.

A note on the FeedBurner Help Group site attributed to Matt S. (who could be Matt Shobe, FeedBurner's co-founder and CDO) stated that no applications for the network are being accepted, paidContent reported.

“...we expect the broad variety of options provided through AdSense (including the new AdSense for Feeds product, powered with FeedBurner feeds) will give publishers valuable new revenue-earning potential,” the note stated.

According to Search Roundtable, since April, FeedBurner's Ad Network has been paying out 10 to 25 percent of what it used to pay out.

“I suspect because the FeedBurner team is less interested in finding ad partners and more interested in pushing publishers into AdSense,” the Search Roundtable article stated.
