AdMob offers various controls to review and block ads in your apps. These include category, advertiser URL, app install ads, and several other settings. Blocking controls may be applied to a single app or to your entire AdMob account. You can change other blocking controls settings in AdMob, such as allowing additional ad technology vendors in your account.
Allow additional ad technology vendors
Google allows third party vendors used by advertisers to buy your ad slots. Allowing additional ad technology vendors results in more ads being eligible to be shown to your users, and as a result can potentially lead to higher earnings.
Note: This control doesn't override EU user consent, California Privacy Rights Act or other regulatory settings, or the list of allowed ad networks in your account. For more information:
