We strongly encourage Google AdSense publishers to take a look at their Ad Experience Report and address any issues that have been identified. Here’s how.
Using historical information about your campaign and evaluating the contextual signals present at auction-time, Target CPA bidding automatically finds an optimal CPC bid for your ad each time that it’s eligible to appear. Google Ads sets these bids to achieve an average CPA equal to your target across all campaigns using this strategy.
For displaying ads with AdSense for content, publishers receive 68% of the revenue recognized by Google in connection with the service. For AdSense for search, publishers receive 51% of the revenue recognized by Google.
Google AdSense draws ads from the Google Ads programme to display on your pages. Even though the number of advertisers in the Google Ads programme is growing continually, Google might currently only have a limited number of ads that are targeted toward the content of any specific page.
