Yesterday, Google revealed the revenue share of their AdSense program. They said within the upcoming months they would be adding the revenue share figures to the AdSense console. But it is actually in there as of yesterday.
AdSenseAdvisor, or Google's Rohit, said in a WebmasterWorld thread:
The AdSense for Content and AdSense for search revenue numbers mentioned in today’s blogpost are now being displayed in the new AdSense interface (still in beta). These numbers will also be available in the existing interface soon as well.
My first instinct was to check the AdSense reports and see a new column for revenue share, but it was not there. A Google AdSense Help thread aided me in finding it under the "account settings" section of the AdSense console.
Here is a picture:
As you can see, Google lists the revenue share by product under the "Active products" section. They only list the revenue share for "AdSense for Content" and "AdSense for Search," the others they are not sharing the information on yet.
