Block ads by user-based data

You can block Google Demand sources, including the Google Display Network (GDN) and Display & Video 360, from showing ads based on user interest categories, or from serving remarketing ads. This setting applies across all of your inventory and targeting, at the product (web property) level.

This control relates to the use of non-signed in visitation information. The Enable Google signed-in, cross-device personalized ads control allows Google demand sources to use signed-in Google user data from a publisher's Ad Exchange-eligible inventory to show personalized ads to signed-in users based on their interests, demographics, and Google account information.

For settings that apply to all other buyers, use the "Cookies and data uses (non-Google Demand)" settings.

Get started

  1. Sign in to Google Ad Manager.
  2. Click Protections and then Network level
  3. Click the medium on which you want to control the display of ads, such as Mobile app.
  4. Slide the setting to Disabled for either of these categories:
    • Interest-based category ads (non-signed in users): Block Google Demand sources, including GDN and Display & Video 360, from showing ads based on user interest categories, and using non-signed in user visitation information from your site to help create these interest categories.
      Keep in mind that by opting out of showing interest-based ads, you’ll decrease the number of ads competing to appear on your website, which may decrease your earnings.
    • Remarketing ads: Block Google Demand sources, including GDN and Display & Video 360, from serving remarketed ads.
  5. Click Save.
