The Google AdSense revenue share has been the top secret for past years. At last, Google decided to be more transparent and shared the revenue shares for two AdSense products: AdSense for content and AdSense for search.
AdSense for content: Publisher (68%), Google (32%)
AdSense for search: Publisher (51%), Google (49%)
Google is quite confident about their revenue split and ask publishers to focus on the total revenue generated instead.
We believe our revenue share is extremely competitive. However, revenue shares alone can be misleading, so we encourage you to focus on the total revenue generated for your site.
You can also check the Google AdSense revenue share details in your AdSense “Account information” section.
Note that the screenshot was taken from my Google AdSense (BETA) account. You might not get the same info.
My two cents
To my surprise, the revenue gives to publisher is more than I expected. I thought Google takes at least 60%. Hopefully Google will reveal more revenue share info for other AdSense products soon.
Are you happy with the AdSense revenue share amount?
