How to do cross-domain tracking

Cross-domain tracking in Google Analytics is a technique that allows you to track a user's session as they navigate between different domains or subdomains. Without cross-domain tracking, Google Analytics will treat each domain or subdomain as a separate session, which can lead to inaccurate tracking and skewed data. To implement cross-domain tracking in Google Analytics, you will need to do the following: Add the same Google Analytics tracking code to all the domains or subdomains you want to track. Set up cross-domain tracking by adding the domains or subdomains to the Referral Exclusion List in your Google Analytics account. This will ensure that clicks between the domains or subdomains are tracked as part of the same session. Use the _linker parameter in your Google Analytics tracking code to pass information between domains or subdomains. This will allow Google Analytics to associate data from different domains or subdomains with the same user session. Once you have implemented cross-domain tracking in Google Analytics, you will be able to track user behavior across multiple domains or subdomains, including the source of traffic, user engagement, and conversions. This can provide valuable insights into how users interact with your website or online business, and help you optimize your marketing and conversion strategies accordingly.
