What is deadlinkchecker?

About

deadlinkchecker is a web crawler service operated by DLC Websites that crawls customer websites to identify and report broken links (404, 500 errors, etc.). It helps website owners maintain site quality and SEO rankings by detecting problematic links. You can see how often deadlinkchecker visits your website by setting up Dark Visitors agent analytics.

Expected Behavior

Developer helpers generally visit websites on direct behalf of a user who is evaluating some feature or attribute. Visits can be one-off or part of a larger crawl.

How Do I Block deadlinkchecker?

⚠️ Manual Robots.txt Edits Are Not Scalable
New agents are created every day. Instead, serve a continuously updating robots.txt that blocks new agents automatically.
Set Up Automatic Robots.txt

You can block deadlinkchecker or limit its access by setting user agent token rules in your website's robots.txt. Set up Dark Visitors agent analytics to check whether it's actually following them.
