Disallow: /Frequently Asked Questions
Should I Block ProjectShield Url Check?
Only if nobody you work with uses it. ProjectShield Url Check 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 ProjectShield Url Check right now.
Does ProjectShield Url Check Respect Robots.txt?
No. ProjectShield Url Check 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 ProjectShield Url Check 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, ProjectShield Url Check sees only public pages.
Why Is ProjectShield Url Check Visiting My Website?
Someone pointed ProjectShield Url Check at your site, most likely your own team. Uptime monitors, performance testers, and audit tools only visit the sites they are configured to watch.
