Broken Link Checker

Enter a list of URLs and check which ones return 404 errors or other HTTP error codes. The tool fetches each URL and reports its status code — ideal for SEO audits, blog maintenance, and ensuring your content links are all working. No signup required.

🌐 API Integration Required

This tool needs a backend API to check external URLs. Options:

  • Use a serverless function (Next.js API route)
  • Integrate with RapidAPI URL checker APIs
  • Use PageSpeed Insights API (for speed checker)

Frequently Asked Questions

How does the broken link checker work?▼
It sends fetch requests to each URL you provide and checks the HTTP response status code. A 200 means the link is working; 404 means not found (broken); 301/302 means redirect; 5xx means server error.
Are there limitations due to browser CORS policies?▼
Yes. Some websites block cross-origin requests, causing the checker to report a network error even if the link is technically live. This is a browser security limitation, not a bug in the tool.
Why do broken links hurt SEO?▼
Broken links create a poor user experience and waste Google's crawl budget on dead pages. They also break link equity flow in your internal linking structure, which can hurt rankings.
How many URLs can I check at once?▼
Paste up to 100 URLs for a batch check. The tool checks them sequentially with a short delay to avoid being rate-limited by the target servers.
What HTTP status codes indicate a problem?▼
404 (Not Found), 410 (Gone), 5xx (Server Error), and connection timeouts all indicate broken or problematic links that should be fixed or removed.
