Broken Link Checker | Free Dead Link Finder - SEOKit

Free broken link checker. Paste HTML or a list of URLs to find dead links, 404 errors, and redirect chains. Keep your site healthy for SEO.

What is Broken Link Checker?

A broken link checker scans URLs to identify dead links (404 errors), server errors (5xx), and redirect chains. Broken links hurt SEO by wasting crawl budget, damaging user experience, and passing signals to search engines that your site is poorly maintained.

How to Use Broken Link Checker

Paste a list of URLs (one per line) or paste HTML content containing links. Click Check Links to validate each URL. The tool checks the HTTP status of each link and reports which ones are broken (4xx/5xx errors), redirected (3xx), or healthy (2xx). Review the results and fix any broken links on your site.

How Broken Link Checker Works

Enter URLs or paste HTML content. The tool extracts all links, validates URL format, and checks each one by making HTTP HEAD requests. Results show the HTTP status code, response time, and link status (healthy, broken, redirected). A summary shows total links checked and the breakdown by status.

Common Use Cases

  • Find and fix 404 errors on your website
  • Audit external links pointing to dead pages
  • Identify redirect chains that slow down crawling
  • Check links before publishing new content
  • Maintain site health as part of regular SEO audits

Frequently Asked Questions

Why are broken links bad for SEO?

Broken links waste crawl budget, create poor user experience (increasing bounce rate), and signal to search engines that your site is poorly maintained. They also prevent link equity from flowing to the target page.

How often should I check for broken links?

It is recommended to check for broken links at least monthly, or after any major content updates. Large sites with many external links should check more frequently as external sites may change or go offline at any time.

What is a 404 error?

A 404 error means the requested page was not found on the server. This happens when a page is deleted, moved without a redirect, or the URL contains a typo.

How do I fix broken links?

For internal links, update the URL to point to the correct page or set up a 301 redirect from the old URL. For external links, either update the link to a working URL, find an alternative resource, or remove the link entirely.
