For a long time, the percentage of revenue Google shares with publishers on the Adsense program has been subject to much speculation. Today these were finally laid to rest when Google publicly announced, for the first time, how much revenue the company shares with content publishers through the Adsense program.
In a blog post, Google disclosed that publishers earn 68% of the revenue for Adsense for content and 51% of revenue for Adsense for search.
AdSense for content publishers, who make up the vast majority of our AdSense publishers, earn a 68% revenue share worldwide. This means we pay 68% of the revenue that we collect from advertisers for AdSense for content ads that appear on your sites. The remaining portion that we keep reflects Google's costs for our continued investment in AdSense — including the development of new technologies, products and features that help maximize the earnings you generate from these ads. It also reflects the costs we incur in building products and features that enable our AdWords advertisers to serve ads on our AdSense partner sites. Since launching AdSense for content in 2003, this revenue share has never changed.
We pay our AdSense for search partners a 51% revenue share, worldwide, for the search ads that appear through their implementations. As with AdSense for content, the proportion of revenue that we keep reflects our costs, including the significant expense, research and development involved in building and enhancing our core search and AdWords technologies. The AdSense for search revenue share has remained the same since 2005, when we increased it.
Over the next few months Google will also begin showing the revenue shares for AdSense for content and AdSense for search right in the AdSense interface.
At this time, the percentage of revenue share for other AdSense products including AdSense for mobile applications, AdSense for feeds, and AdSense for games are not disclosed.
