In the rapidly evolving landscape of online analytics, gaining insights into user behavior across multiple domains is paramount for businesses seeking a comprehensive understanding of their audience. Google Analytics 4 (GA4) addresses this need through its robust cross-domain tracking capabilities. In this article, we will delve into the intricacies of cross-domain tracking in GA4, exploring its functionality, setup process, benefits, and troubleshooting tips.
What is Cross-Domain Tracking in Google Analytics 4?
Cross-domain tracking in GA4 is a pivotal feature that enables businesses to monitor user interactions seamlessly across different domains or websites. Think of cross-domain tracking as a bridge connecting the islands of your online presence. It seamlessly tracks user activity across multiple entities that share the same GA4 measurement ID. Whether you’re an e-commerce giant with a separate checkout domain or a content publisher with a dedicated blog subdomain, cross-domain tracking ensures you see a unified view of user journeys that span various web properties and not just fragmented snapshots.
For example, you might have a website set up for your general business and one for your online store. It makes sense that you’d want to follow a user between these two sites to get a full picture of their journey and see the behaviour that led to a purchase. By default, Analytics will not track your users as they move from site A to site B. Instead, you have to set up cross-domain tracking to follow them from one website to another. Cross-domain tracking is important because it lets you accurately track your users without augmenting your metrics.
How Does Cross-Domain Tracking Work in Google Analytics 4?
GA4 achieves cross-domain tracking through first-party cookies. As users navigate from one domain to another within a specified list, GA4 ensures the continuity of the user’s session by sharing cookie information. When a visitor navigates from domainA.com to domainB.com, Google Analytics 4 will pass a special parameter to domainB.com’s URL. Thanks to that parameter, the GA on domainB.com will be able to update Google Analytics 4 and will understand that it’s actually just one person navigating between two websites. This meticulous process enables GA4 to attribute user actions accurately to the same individual, even when they traverse different domains.
How to set up GA4 Cross-Domain Tracking?
Implementing cross-domain tracking in GA4 involves a step-by-step process:
Step 1: Update GA4 Configuration:
Begin by ensuring that your GA4 property is correctly configured. Implement the GA4 code on all relevant domains.
Go to the Admin of Google Analytics > Data Streams and select web data stream.
Go to Configure Tag Settings.
Click Configure your domains.
Enter all domains that should be included in the cross-domain tracking setup. Then hit save.
That’s it! You don’t need to configure the referral exclusion list for this. GA will handle that automatically.
Benefits of Cross-Domain Tracking
Comprehensive User Journey Insights
Cross-domain tracking empowers businesses with a holistic view of the customer journey. This insight proves invaluable for understanding how users navigate through various touch points before conversion.
Ensuring that user actions are accurately attributed to the correct source, cross-domain tracking allows businesses to make informed decisions based on reliable data.
Enhanced Marketing Analytics
For businesses employing marketing strategies across diverse domains, cross-domain tracking facilitates a more accurate assessment of campaign effectiveness and user engagement.
Why is My Cross-Domain Setup Not Working Accurately?
Despite the robust nature of GA4’s cross-domain tracking, issues may arise. Common reasons for inaccuracies include:
- Incorrect Configuration: Ensure that GA4 is correctly configured on all domains, and the cross-domain parameters are correctly implemented.
- Browser Settings: Some users may have restrictive browser settings that hinder cross-domain tracking. Encourage users to enable cookies for a seamless experience.
- Redirects and Pop-ups: Certain redirects or pop-ups might disrupt the tracking process. Test thoroughly and address any issues with redirects or pop-ups.
Imagine shattering the walls between your website, app, and blog, revealing a seamless picture of your customer journey. That’s the power of cross-domain tracking in GA4. It’s not just “powerful,” it’s transformative. Gone are the days of fragmented data. Now, you can see how users truly navigate your digital empire, from blog discovery to app conversion.

- Can I Set Up Tracking for a Domain That I Do Not Own or Regulate? Like Payment Gateway Pages?
In most cases, cross-domain tracking requires control over the domains involved. However, for scenarios involving third-party payment gateways, collaboration with the service provider is necessary to ensure accurate tracking. Communication and coordination with the payment gateway provider are crucial for successful implementation.
- Do I Need Cross-Domain Tracking for Subdomains?
While GA4 inherently tracks user interactions within a subdomain, cross-domain tracking becomes essential when monitoring user journeys that span multiple domains. If your online presence involves distinct domains, implementing cross-domain tracking ensures a seamless and accurate analysis of user behaviour.
- How Do I Test Cross-Domain Tracking?
Here’s how to test your cross-domain setup:
- Click a link: On your first website, find a link that leads to the second website you configured for cross-domain tracking. Click that link.
- Check the URL: Once you reach the second website, examine the URL. If everything is working correctly, you should see a parameter called `_gl=` followed by a long string of characters.
- Compare cookies: Open your browser’s developer tools and look for the cookies named `_ga`. Check if the value of this cookie is the same across both domains. You can also look at the “Domain” column to ensure it matches for both cookies.
If you see the `_gl` parameter in the URL and the `_ga` cookie values are identical across both domains, your cross-domain setup is likely working correctly.
- Take a screenshot of the cookies for reference.
- Repeat this test with different links and across various devices and browsers to ensure consistent results.
- Consider using browser extensions like Google Tag Assistant or GA Debugger for more advanced verification.
