Ad review center & blocking controls

Find ads in the ad review center

The Ad review center, offers several features to help you find specific ads to review and block.

Ad review center search bar

Filter or search

The search box at the top of the Ad review center lets you restrict which ads you see, for example, by language, ad type, ad size, etc.

To filter or search for ads:

  • Type in the search box or click the search box and select a filter.

    You can choose from the following filtering options:

    • Text: Find ads with matching ad text or destination URLs.
    • Publisher domain: Filter ads based on which of your apps they appeared in.
    • Newest ads: Search for ads that have appeared in your apps in the last 1, 3, or 7 days.
    • Ad network: Search for ads from a specific ad network.
    • Language: Filter based on the language that has been detected for ads. To determine ad language, we look at various factors including the landing page of the ad as well as its content, which means you might see ads with images or text in a different language to the one you filtered on. The list is ordered by the percentage of ads in each language.
      For example, let's say you have ads in five languages (English, Spanish, Italian, Portuguese, and Japanese), and the distribution totals for each language are: English (20), Spanish (40), Italian (25), Portuguese (5), and Japanese (10). The list would then display the languages in the following (descending) order: Spanish, Italian, English, Japanese, and Portuguese.
    • Size: Filter based on the size of the ads shown in your apps. The list is ordered by the percentage of ads of each size.
    • Ad type: Filter by image, text, or rich media ads.
    • Click string: Search for ads based on their tracking URL or click string. You'll need to find the ad's click string first.

Image search 

You can use the Ad review center's image search function to help you find and review image ads. For example, you could upload a picture of a competitor's logo and use it to search for image ads containing their logo.

To search for ads that match an image:

  1. Click Search by image.
  2. Drag or upload your image.
    Your image can be a maximum of 2MB in size, and its largest dimension should be less than or equal to 1024 pixels. The supported image file formats are: JPEG, GIF and PNG. However, ad matches can only be identified with an original PNG. Learn more.
    Distorting the image will affect the search results. Be sure that you haven't distorted the image by zooming in or out. Also, if you are using an image that was emailed, be sure to download the image to your computer rather than copying the image to avoid distortion. 
  3. Click Search.

During the search, Ad review center may find ad matches, as well as visual matches, for the ad you're searching for. Ads will be labeled as ad matches or visual matches in the search results.

  • An ad match is the instance of the ad you uploaded. Search finds the ad you uploaded based on the ad and time it served. AdMob then allows you to block it, or lets you know the source of the ad.  

    An ad match may or may not be visually exact to the uploaded ad. Blocking the ad match can prevent it from showing in your app, however it may still serve from your other ad sources.
  • A visual match is a ad that is visually exact or very similar to the uploaded ad you're searching for, but may or may not be an exact ad match. 
Note that while image search supports most file types and ad types, it might not always return all available images ads.

You can also use image search to identify the source of a ad. Learn more.

Related ads

The Ad review center also offers the ability to find related ads. Ads are considered related if they have a similar destination page, or are connected by a similar subject (e.g., a brand, a person, an object etc.).

To view related ads:

  • Hover over an ad and click Find related ads.

    Any related ads found will appear in a filtered page labeled "Related ads". From here, you can choose to either click Block all or Mark all as reviewed.
