What is the AMP_TOKEN cookie?
Contains a token code that is used to read out a Client ID from the AMP Client ID Service. By matching this ID with that of Google Analytics, users can be matched when switching between AMP content and non-AMP content. Reference: https://support.google.com/analytics/answer/7486764?hl=en.

How to stop it
Declining non-essential cookies in a site's consent banner should stop AMP_TOKEN being set on later visits. Blocking third-party cookies in your browser settings stops the third-party kind everywhere, and clearing cookies for a site removes any it already set.

Understanding this page
- How cookie lifetimes work, and why a 13-month _ga matters
What a cookie's "expires" field actually controls, why Google Analytics ships a 2-year default that many sites cut down to 13 months, and how Safari's 7-day cap on script-set cookies changes the picture.
- First-party vs third-party cookies (and why "first-party" still tracks you)
What the distinction actually means technically, why browsers only block one of the two, and how CNAME cloaking, server-side tagging and cookies like _ga let sites keep tracking under their own domain.
- How to block or limit trackers
Browser privacy settings, content blockers, Global Privacy Control and clearing cookies compared honestly — what each one actually stops, what it doesn't, and what it costs you in return.
