Google disclosed today for the first time in their history, the percentage of advertisement amount that they pay out to the publishers via their AdSense platform.
AdSense along with AdWords is the primary revenue generating engine for Google. All these days, the publishers on AdSense network had no clue about the percentage of cut that Google was retaining. There were many speculations in the past that Google keeps 50% of the ad revenue from the advertisers and only gives 50% to the publishers.
Today, Google has come out with a blog referring to the fact that they wanted to be more transparent to their users. It is a very good move and is a positive step in the right direction.
