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.

⚠️ Manual Robots.txt Editing Is Not Scalable
New agents are created every day. We recommend setting up Dark Visitors Automatic Robots.txt if you want to block all agents of this type.
