How to setup cross domain tracking in GA4
In this guide, you will learn what cross-domain tracking is and how to set it up in GA4.
What is Cross domain tracking and why use it?
Cross domain tracking is a technique used to track the behavior of a user across multiple domains in a single session. It allows a business to track the user’s interactions with their website, even if the user moves from one domain to another. This is useful for businesses that have multiple subdomains or operate on multiple domains, as it allows them to get a more comprehensive view of the user’s behavior and interactions.
To implement cross-domain tracking, a business will need to use a tracking tool, such as Google Analytics, that supports cross-domain tracking. This typically involves adding a piece of tracking code to each domain and setting up the tracking tool to recognize when a user moves from one domain to another.
By tracking users across multiple domains, businesses can get a better understanding of how users are interacting with their websites and how they are progressing through the customer journey. This can be used to optimize the user experience and improve marketing efforts.
