I was just going through some changes and noticed Google using a new method to show Ads. Right below the current Google AdSense ads there is a new link which says Show More Ads. This link takes the user to a new page which shows relevant ads to the user.
This was earlier also reported in Search Engine Land. Obviously I was a bit late to spot it. Have you been seeing the new functionality in AdSense ads?
The question though is whether user would be enticed to click on it and who will be actually credited for the clicks for the Ads. I am not sure as I have not heard much about this on the AdSense blog yet or I may have been ignorant about this.
