Google Adsense publishers would have noticed a scrollbar popup on the corners of their website ads. Clicking on the Ad Scrollbar up or down makes the ad space display a new set of advertisements.
Google Adsense has been constantly updating its marketing strategy to be beneficial for advertisers and publishers. The recent drop in Click Thru Rates, Pay Per Click and Conversion rates has forced PPC companies to try new strategies and increase the revenue on both ends.
Recently, Google had some of its Google Adsense guidelines changed and had requested publishers to differentiate between an Ad and the site content.
However, there are mixed responses from publishers and advertisers whether the new scrollbar would increase or decrease the click thru rate.
