Send non-personalized ad requests to third-party RTB buyers

Beginning on October 21, 2021, Google will start sending bid requests for non-personalized and restricted data processing ad requests to third-party RTB bidders.

This help center will be updated periodically to ensure you have the latest information.

The information in this article only applies to Authorized Buyers and Open Bidding.

Non-personalized ads are ads that are not based on a user’s past behavior. They are targeted using contextual information, including coarse geo-targeting based on current location and content on the current site or app. Google disallows all interest-based audience targeting, including demographic targeting.

Google Ad Manager provides tools to help you respect user preferences and assist you with your compliance with local regulation:

• IAB TCF v2.2: The TC string contains information about the ad partners to which a user has granted consent. Learn more about TCF v2.2 and non-personalized ads
• European regulations: You can select non-personalized ads on the ad requests originating in the EEA, the UK, and Switzerland by tagging the ad request as non-personalized or by setting your account to non-personalized ads in the European regulations settings in Privacy & messaging. Click Privacy & messaging  European regulations  Settings to access the settings. When a valid TC string is detected, Google will handle the ad request as described in Publisher integration with the IAB TCF v2.2.
• US state regulations: You can restrict data processing on the ad request by tagging the ad request as restricted data processing, or by setting your account to restrict data processing in the US state regulations settings settings in Privacy & messaging. Click Privacy & messaging US state regulations  Settings to access the settings.

When a valid TC string isn’t detected, non-personalized ad requests originating from different regions may be treated differently:

• EEA, the UK, Switzerland, and applicable US states: You can use the European regulations settings and US state regulations settings in Privacy & messaging to select the partners that will receive these non-personalized and restricted data processing ad requests in these regions. These settings will apply for both non-personalized and personalized ad requests, if you have allowed personalized ads.
• Brazil: For ad requests originating from Brazil, all bid requests will be sent to bidders that are part of the Ad Technology Providers for the LGPD list.
• Other regions: Non-personalized ad requests outside of the previously noted regions will be sent to all bidders, subject to other protections.

Non-personalized bid requests sent to third-party RTB bidders will be labeled with appropriate privacy signals, and user identifiers (such as google_user_id, hosted_match_data, any device advertising IDs, and session_id) will be removed from bid requests for non-personalized ads. User-Agent information will be generalized and truncated IP address will be removed in bid requests for non-personalized ads. Learn more about non-personalized bid requests
