Google AdSense Changes From CPC to CPM
Dan Taylor (via Hacker News):
Today, website owners use a combination of direct sales, ad networks and sell-side platforms to sell their ad space, often using multiple technologies simultaneously.
This is why we are making two changes: updating AdSense’s revenue-share structure and moving to paying publishers by impression. These changes will provide a consistent way for publishers to compare the differing fees across the various technologies they use to monetize and will provide even greater transparency into the media-buying process.
Based on our tests, we don’t expect publishers to see a change in their earnings as a result of these updates.
Is it a way to admit they can no longer reliably track user clicks thanks to browsers that try to protect user privacy (Safari) ?
