Appeal process for app-level violations
For app-level violations, you’ll be notified in the AdMob Policy center and via email. You can review the details of the violation in the Policy center of your AdMob account. Please carefully review the description on the violation and what steps, if any, you can take to fix the issue. Once you’ve made the appropriate changes to your app, you can request a review of your app in the Policy center. If your appeal is rejected, we suggest you review the policy details and the changes you have made again to ensure that the issue itself has been solved. After that, please submit another appeal for the violation through the Policy center.
