Track users across domains

If the flow of your website user experience goes from one domain to another (e.g. to, you should set up your Universal Analytics tags to track those visits as one. Without this functionality, Google Analytics will track the user as two separate visitors, which will inflate then number of users appearing in your reports. This will occur even if both domains use the same Tag Manager container and Analytics account.

To configure your Universal Analytics tags to handle multiple domains as one:

  1. Open your Google Analytics Settings Variable or Universal Analytics tag for editing.
  2. Navigate to More Settings and then Cross Domain Tracking.
  3. In the Auto Link Domains field, enter a comma-separated list of domains.
    Note: If multiple variables or tags use the same list of domains, consider using a constant string variable.
  4. Save your changes and publish the container.
