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

This article describes how to set up the Google Cookie Matching Service for Google Ad Manager and DV360 (Tealium-hosted) tag in your Tealium iQ Tag Management account.

Google’s Cookie Matching Service enables a buyer to associate the cookie that identifies a Tealium visitor, and the 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.

  • Use mappings to override standard config
  • If left blank, Tealium Account and Tealium Profile will be automatically populated.
  • In allowed regions, sends the following server-side attribute back to Tealium: google_gid
