Frequently Asked Questions
Should I Block deadlinkchecker?
Only if no one on your team relies on it. deadlinkchecker 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 deadlinkchecker.
Does deadlinkchecker Follow Robots.txt Rules?
No. deadlinkchecker 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 deadlinkchecker Access Private Content?
Only when configured with access. A team may grant deadlinkchecker credentials to monitor staging sites or private health endpoints. Without those credentials, it sees only public pages.
Why Is deadlinkchecker Visiting My Website?
Someone, most likely on your own team, configured deadlinkchecker to check your site. Uptime monitors, performance testers, and audit tools visit only the sites or endpoints they are told to watch.
How Can I Tell if deadlinkchecker Is Visiting My Website?
Agent Analytics tracks deadlinkchecker 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 "deadlinkchecker". Look for repeated checks of the same pages or endpoints at regular intervals. Because deadlinkchecker does not publish a verification method, any client can claim its identity and a log match is only a clue.
