You can use the serving restriction breakdown in your reports to compare personalised ads to non-personalised ads. This can help you understand which restrictions lead to ads not being personalised, and how these restrictions impact your revenue.
Note: Serving restriction data is not available in AdSense reporting prior to 11 October 2024.
When you add this breakdown to your reports, you can view which serving restrictions are affecting your AdSense traffic and how:
- Limited ads: Ads that are limited because of the absence of consent for the use of cookies, mobile device identifiers or other local storage.
- Restricted data processing (RDP): You've enabled restricted data processing (for example, using AdSense’s blocking controls).
- Non-personalised ads (NPA): You've enabled non-personalised ads
- Basic ads: IAB TCF v2.2 basic ads were served.
- Personalisation disabled: May occur when iOS users have opted in to Limited Ad Tracking or haven’t provided consent under the AppTrackingTransparency (ATT), and there's no other available user identifiers. May occur when Android users opt out of ad personalisation. Includes any other cases where personalisation wasn’t feasible.
- No restriction: Ads are personalised using available user identifiers.
Some ad requests may fall into multiple categories in this list. In these cases, the ad request is sorted into the first applicable category according to the order shown here.
Ad serving restrictions due to policy issues are not included in the serving restriction breakdown. Review any policy issues and their effect on ad serving in the Policy centre of your account.
