If you are wondering about Cross-Domain Tracking, it is because a professional has told you about it in the context of an audit. Do you need it for your business? What is it good for? What does it do for you?
What is Cross Domain Tracking?
Cross-Domain Tracking allows you to track the behaviour of the same user on several sites that belong to the same business.
For example, you have a site called monbusiness.com but the purchase or reservation is made via a sub-domain called app.monsite.com. Cross-domain tracking allows you to track the user who navigates from one domain to another as one.
Cross-Domain tracking is also known as multi-site tracking, multi-domain tracking or cross-site tracking.
