How do I set up cross-domain tracking between two websites in GA4?

Asked on Sep 14, 2025

Answer

To set up cross-domain tracking in Google Analytics 4 (GA4), you need to configure your data stream settings to recognize user sessions across different domains. This ensures that user interactions on both websites are tracked as part of a single session.

Sign in to your Google Analytics account.
Navigate to Admin → Data Streams and select the web data stream for your website.
Click on "More Tagging Settings" and then "Configure your domains".
Add the domains you want to track under "Domains", ensuring both websites are listed.
Save the changes to apply cross-domain tracking.

Additional Comment:

Ensure that both websites have the GA4 tracking code implemented correctly.
Cross-domain tracking requires that both domains are under your control or have permission to be tracked together.
Test the setup by navigating between the domains and checking the Real-Time report for consistent session tracking.
