Suggestions that Adsense returns up in face of Yahoo! competition

Jason Calacanis has suggested that the percentage of return to publishers from Google’s Adsense may have increased due to the imminent entry of Yahoo! into the broader blog advertising marketplace.

According to his figures, the boost is around 10-15%.

Personally I cant see this in my own figures, but I’m in the middle of inventory changes at the moment across the network. Can any one else see a boost? Leave a comment.
