Adsense Officially Announces the launch of their new Ad Format of 200 x 200. Google Calls it to be said as Small Square! As Google Adsense Blog states, it is to be launched under the reviews of the publishers of Google Adsense. Adsense is lately doing a lot of improvements to bring out more efficiency to their publishers - advertiser system to ultimately bring out more participation and a WIN - WIN situation to them.
It is said that Google is also experimenting with Leader Board and other ads, which looks to be premium. But there is no official confirmation about its launch as Adsense Blog states nothing about it. We will soon hear more about it.
