Today I saw two arrows next to “Ads By Google” in one of my Adsense Ads. After spending some time on researching I found out that this is the Google’s upcoming feature in adsense for publishers. These ads are not activated yet on every publisher’s account because google engineers are testing it on different accounts.Clicking on these arrows, visitors can scroll up and down to see more contextual ads while staying on the same page. I think they are using AJAX Technology in these slider ads. Google is improving its ads technology day by day as we have seen lot of improvement in the Google Adsense in the year 2007.
Some of them are Optimization Tips, Rounded Corners, Ad Management & payments through Western Union.
I hope that publishers will get more and more $$$ with this cool feature once it is rolled out to production servers.
