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?

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.

# In your robots.txt ...

User-agent: deadlinkchecker # https://darkvisitors.com/agents/deadlinkchecker
Disallow: /

⚠️ 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.
