An AI opt-out signal is set
A Content-Signal directive is telling AI systems not to use this site. CDNs inject this by default on some plans, so it is frequently set without the owner deciding to set it. 77 sites had this problem when we measured them in the last 7 days. The list gives each one with its domain, name where known, platform, every technology we detected, its A–F grade with all its findings, location where known, and what it serves AI crawlers.
- 77 sites, last 7 days
