Account Linking

The Principle of Account Linking

Legal authorization to share MMM data on behalf of a data owner is now embedded directly in-platform through cross-product Account Linking with Google Ads Data Manager (GADM) or Display & Video 360. When a link is established, the advertiser reviews and accepts the Terms of Service (TOS) digitally.

Prerequisites for Vendors

A vendor cannot initiate a data project, define campaigns, or request files for an advertiser until they have successfully linked at least one active Google Ads Customer ID or a Display & Video 360 account ID.

To get started:

  1. Create an Advertiser Workspace by clicking + New Advertiser.
