How can I tell if cross domain tracking is working properly with gtm?

To determine if cross-domain tracking is working properly with Google Tag Manager (GTM), you can follow these steps:

1. Check if the tracking code is firing: Open the Google Tag Manager preview mode and navigate to the page where you have implemented cross-domain tracking. Check if the GTM tags are firing on that page.
2. Verify the cookie domain: In the GTM container settings, check the cookie domain under the "Cross-domain tracking" section. The cookie domain should be set to the top-level domain of your website.
3. Check the link decoration: If you have set up link decoration for cross-domain tracking, check if the links are properly decorated with the linker parameter (_ga). You can use the Google ****ytics Debugger extension to verify this.
4. Check the referral source: In Google ****ytics, check the referral source of the sessions to see if they are coming from another domain. If cross-domain tracking is working correctly, the referral source should show the full URL of the previous domain.
5. Test cross-domain tracking: You can perform a test by navigating from one domain to another and checking if the session is carried over. Open the Google ****ytics Debugger extension and check if the _ga parameter is passed from one domain to another.

By following these steps, you can verify if cross-domain tracking is working properly with GTM. If you encounter any issues, you can troubleshoot them by reviewing the GTM setup and consulting the Google ****ytics do***entation.
