If you set a CNAME to point to a third-party, the cookies become in fact first-party and cross-domain tracking no longer works.
- uallo 7y agoNo it is not OK. Cross-domain tracking still works. While every domain has its own cookie, it is extremely simple to use fingerprinting to connect those cookies to a single user.
