Cookie Deprecation
The industry-wide phase-out of third-party cookies, forcing a shift to first-party measurement.
Also known as: Cookie deprecation · Cookieless
Cookie deprecation is the ongoing phase-out of third-party cookies by browsers and regulators, which breaks cross-site ad tracking and attribution that depended on them.
It pushes measurement toward first-party data and consented signals — exactly the surfaces creator commerce uses, so its attribution survives the change.
