What is cross domain click?

A cross-domain click refers to a user interaction where a click on one website leads to navigation to a different domain. This typically occurs when a user clicks a link on Site A that directs them to Site B.

Cross-domain clicks are important in web analytics, advertising, and user experience design. They can present challenges for tracking user behavior, as browsers implement various restrictions on cross-domain interactions to protect user privacy.

What is cross domain event?

A cross-domain event in Tracardi is a mechanism that allows the transfer of a customer's profile ID from one domain to another, maintaining continuity of customer identification across different owned websites. Here's how it works:

  1. Configuration: Enable the feature by adding trackExternalLinks to the tracker settings, specifying the domains you own.

  2. Link Rewriting: The JavaScript code automatically rewrites links on the page, adding __tr_pid (profile ID) and __tr_src (source ID) parameters to URLs that match the specified domains.

  3. Profile Transfer: When a user clicks a modified link, these parameters are passed to the destination domain.

  4. Profile Recognition: On the new domain, Tracardi checks for these parameters. If found and valid profile is available then it merges the referred profile with an existing local profile

  5. Session Management: Tracardi invalidates the session if the profile ID is incorrect and creates a new one if necessary.

This approach ensures consistent customer identification across your owned domains, improving user tracking and analytics capabilities.
