Google launched a new capability in AdSense allowing Google-certified ad networks compete directly within AdSense, which means that advertisers from these third-party networks will be able to compete with AdWords advertisers to show on the Google Content Network.
These new capabilities will automatically be enabled for your account, & you'll see a new section in your Ad Review Center where you can permit or block specific ad networks or all networks except AdWords. note that we'll gradually be adding new ad networks to AdSense accounts over the next few months, so you won't see any immediate impact on your ads or your earnings.
They are currently only accepting ads from Google-certified ad networks in North America & Europe, but they will make this feature obtainable to ad networks in additional parts of the world in the future.
To ensure the quality of the ads that appear on AdSense publisher web-sites, Google will certify all participating ad networks for adherence to our standards for user privacy, ad quality, & speed. Some participating ad networks use targeting methods similar to Google's interest-based promotion to show more relevant ads to users on the sites they visit. These ad networks won't be allowed to collect information from your site for the purpose of later interest-based promotion, but we'll permit networks that comply with user privacy guidelines to show ads using these tools. Publishers can opt out of user interest targeting from these ad networks, & Google has changed our requirements for third-party ad serving to reflect this.
