Disallow: /Frequently Asked Questions
Should I Block Do Not Track Verifier?
Only if nobody you work with uses it. Do Not Track Verifier is the kind of tool a team points at its own site for uptime checks, performance tests, and audits. If someone on your team relies on it, blocking it silently breaks their monitoring. Almost none of the top websites we track have robots.txt rules for Do Not Track Verifier right now.
Does Do Not Track Verifier Respect Robots.txt?
No. Do Not Track Verifier is not expected to honor robots.txt, so a disallow rule only states your preference. Enforce the block with firewall or server rules, then confirm in Agent Analytics that its requests actually stop.
Does Do Not Track Verifier Access Private Content?
Only if its owner sets that up. Monitoring tools check whatever they are configured to check, which can include staging sites and private health endpoints when a team grants access. Uninvited, Do Not Track Verifier sees only public pages.
Why Is Do Not Track Verifier Visiting My Website?
Someone pointed Do Not Track Verifier at your site, most likely your own team. Uptime monitors, performance testers, and audit tools only visit the sites they are configured to watch.
How Can I Tell if Do Not Track Verifier Is Visiting My Website?
Agent Analytics tracks Do Not Track Verifier visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user agent string contains "Do Not Track Verifier". Look for regular checks of the same pages or endpoints, often minutes apart. Keep in mind that Do Not Track Verifier doesn't publish a verification method, so any client can claim its user agent string and a log match is a hint rather than proof.
