Thanks for all of your feedback -- I just wanted to address some of the questions that have popped up here in the comments section.
The 68% revenue share for AdSense for content applies to all online publishers, and is not an average revenue share. If you're showing AdSense for content ads on your pages, you're receiving 68% of the amount advertisers pay for those ads. While the revenue share can vary for some major online publishers with whom we negotiate individual contracts, these amounts are not in any way averaged together. Also, there isn’t anything additional taken off the top. You get 68 percent, period.
