When you set up cross-domain tracking, you can collect data from multiple websites into a single account\u00a0property. This lets you see data from different sites in the same reporting view.<\/p>\n
In some configurations, like with 3rd party shopping carts, this is ideal. In other configurations, however, we recommend that you\u00a0set up multiple views: one view for all of the traffic collected in the cross-domain tracking setup, and a separate\u00a0filtered views\u00a0to display data only from each individual domain. This lets you analyze the traffic from all of the different domains together in one view, and use the other views to analyze data from each domain in a separate set of reports when necessary.<\/p>\n
Multiple domains<\/h2>\n
If you have multiple top-level domains, like\u00a0www.example1.com<\/em>\u00a0and\u00a0www.example2.com<\/em>, you can set up cross-domain tracking to collect and send data from both domains to the same Analytics account property.<\/p>\nSubdomains<\/h2>\nIf you have updated your tracking code to\u00a0analytics.js, then no additional configuration is required to track subdomains.<\/div>\n
You can use cross-domain tracking to collect data from a primary domain, like\u00a0www.example.com<\/em>, and a subdomain, like\u00a0www.subdomain.example.com<\/em>, in a single Analytics account property.<\/p>\nIf you use a 3rd party shopping cart, your traffic probably has to leave your domain to complete a purchase, but you can use cross-domain tracking to keep track of users as they go through the entire checkout process and move between your domain and the domain that hosts your shopping cart.<\/p>\n
IFrame content<\/h2>\n
If you have content that displays on another domain through an iFrame or a similar technology, you can still collect data from that traffic with cross-domain tracking.<\/p>\n
