Google Cookie Matching Service for Google Ad Manager and DV360 (Tealium-hosted) Tag Setup Guide

When using this tag with utag version 4.50 or later, you must set the utag.js always_set_v_id setting to true. This setting ensures that the visitor ID is available for cookie synchronization. For more information, see the utag 4.50 release notes and Considerations for tealium_visitor_id when upgrading to utag 4.50+.

Google’s Cookie Matching Service enables a buyer to associate the cookie that identifies a Tealium visitor and the doubleclick.net cookie that identifies the user for Google. The Tealium-hosted tag allows clients to persist the Google cookie value in AudienceStream for use in the relevant connectors.
