How much do Adsense Publishers Earns from Adsense?

After I published the post “The Adsense Revenue Share” I received plenty of emails asking exactly how much Google is earning and how much are Adsense Publishers earning.

If you are running Google AdSense in all its flavors (for content, for search, for feeds, for mobile), you might have wondered how much money Google is earning from it?
Google reports that for AdSense for Content, it gets 32% which covers for Google’s costs for its continued investment in AdSense. That means, all AdSense publishers earns 68% of ad revenue being paid by advertisers through Adwords to Google, which in turn serves those ads to our sites.
Google’s earnings is also used to payoff the cost that Google incur in building products and features that enables AdWords advertisers to serve ads on our sites. And guess what, this deal has been going on since the launch of AdSense in 2003.
As for AdSense for Search, if you’re running Google’s Custom Search Engine on your sites, the revenue share is 51% for you and 49% for Google. This has been the revenue sharing scheme since 2005 when Google AdSense for Search was launched.
Here is an example of how the split works in actual dollar amounts:

For Each $100 of your earnings in Adsense for Content, Google’s Share made $47.05 thus the total spend by the advertiser was $147.05.

For Each $100 of your earnings in Adsense for Search, Google’s Share made $96.08 thus the total spend by the advertiser was $196.08.

Here are the formulas to calculate Google’s Cut and Advertiser’s spend:

Adsense for Content:
Google’s Cut = Your Earnings x 8 / 17
Advertiser’s Spend = Your Earnings x 25 / 17

Adsense for Search:
Google’s Cut = Your Earnings x 49 / 51
Advertiser’s Spend = Your Earnings x 100 / 51
