All components of your ads—ad text, keywords, ad extensions, and ad customizers—must pass an editorial review. This is a quality check to help ensure that ads are appropriate for potential customers. After you submit a component, the content goes through an initial review to ensure that it meets Microsoft Advertising policies. If your ad components don't raise any flags, they pass the review and become active.
If a component does not pass the initial review, an additional review takes place, which can take several hours based on the volume of reviews moving through the system at any given time. Several situations might trigger an additional review, including:
Most reviews are completed within a day. The editorial status of your ad components can be found in the Delivery column on the Ads, Keywords, or Ad Extensions tab of the Campaigns page, or on the Business data page of your Shared Library. If the review results in a disapproved ad or keyword, see How do I fix a Disapproved or Approved Limited status?
