Frequently Asked Questions
Should I Block Do Not Track Verifier?
Only if no one on your team relies on it. Do Not Track Verifier may support uptime monitoring, performance tests, or audits. Blocking it without checking first can silently disrupt those workflows. Almost none of the top websites we track currently have robots.txt rules for Do Not Track Verifier.
Does Do Not Track Verifier Follow Robots.txt Rules?
No. Do Not Track Verifier is not expected to follow robots.txt directives, so a disallow rule only communicates your preference. Enforce the block with firewall or server rules, then use Agent Analytics to verify that its requests stop.
Does Do Not Track Verifier Access Private Content?
Only when configured with access. A team may grant Do Not Track Verifier credentials to monitor staging sites or private health endpoints. Without those credentials, it sees only public pages.

Someone, most likely on your own team, configured Do Not Track Verifier to check your site. Uptime monitors, performance testers, and audit tools visit only the sites or endpoints they are told to watch.
