What is cross domain measurement?
Cross-domain measurement is a Google Analytics feature that allows you to see sessions from two related sites (such as an ecommerce site and a separate shopping cart site) as a single session, rather than as two separate ones.
How do I check cross domain tracking?
Steps to check cross-domain tracking in Google Analytics

Can you put multiple domains on one Google Analytics?
Yes. This happens when you use 1 AdWords account to handle the ad campaigns of multiple websites, i.e. different TLDs. The main issue is that all clicks will be reported, for all views linked. So site A and B (GA profiles) will show the same AdWords traffic (clicks) but 0 sessions on the clicks that went to the other website.
How to measure a session across multiple domains?
If you want to be able to measure a single session across multiple domains, you need to add your domains to the referral exclusion list. The best way to validate that cross-domain measurement is set up correctly is to use Google Tag Assistant Recordings.
What does it mean to have different cookies for different domains?
Separate domains mean separate user and traffic data. For each separate domain, the standard Analytics cookies determine two simple things: If you have separate cookies set for a domain and a sub-domain, unique users to each are counted independently, and any links between the two sites are counted as referral traffic.
Where are the cookies stored in Google Analytics?
In cross-domain tracking, we share cookie information between two or more domains. This domain can be a primary domain or subdomain. The cookie information that we pass from one domain to another is the client ID. This client ID is stored in the Google Analytics cookie _ga.
