Many publishers choose to use Adbuff as a secondary ad network to AdSense. You are absolutely allowed to run our ads next to your regular AdSense ads and you can rest assured that the ads displayed on your site will always be clean and compliant with AdSense for content policies.
You may notice that our ads are sometimes offered up from Google networks such as DoubleClick, Googleadservices and other Google domains. These are not AdSense ads and do not impact your Ad Unit limits with Google AdSense.
