New layout started showing on my site yesterday (friday) morning.
Really impressive results for ad size 336x280 in the middle of the page.
CTR went up by 1 percentage point and eCPM almost doubled.
For friday, which is usually a very low income day (these sites are targeted to gulf countries where friday is weekly holiday) these results are really encouraging.
Now waiting for weekdays to check the result.
PS: IHHO ad blindness was the major issue for adsense. Now atleast for few days this new layout should show good results.
