The Ad review center in your AdSense account is a powerful tool that enables you to control the ads that appear on your site. Earlier this year, we revamped the tool to provide you with even more robust controls, and today, we’re making an improvement that will help you find and review ads more efficiently. Using the technology behind Google Image Search, you’ll now be able to upload an image file from your computer to search for related image ads; you can then review and take action on the returned ads.

For example, you might want to find and block ads that contain the logo of a competitor. After you upload and search for the logo, we’ll return image ads that contain the logo and which are eligible to appear on your pages. Please note that you can upload images with a maximum file size of 2MB and a largest dimension of 1024 pixels. To try this feature, log in to your AdSense account and visit the ‘Allow and block ads’ tab.

As always, we recommend using filters sparingly, and only in cases where you’d prefer not to have the specific ad or advertiser appear on your pages. Please keep in mind that blocking ads isn’t a revenue optimization tool; it can have a negative impact on your potential revenue since it reduces the competition between ads eligible to appear on your pages.

This feature currently only returns image ads, but we’re planning to support more ad formats in the future. We’ll let you know as soon as any additional functionality becomes available -- in the meantime, feel free to share your feedback about this feature on our AdSense +page or visit our Help Center for detailed instructions.
