Broken Link Checker

Find and fix dead links to improve SEO and user experience

Why You Should Check for Broken Links

Broken links, or "dead links," are links on a webpage that lead to a 404 error page. They are frustrating for users and can severely harm your website's search engine ranking.

How Broken Links Hurt Your Website

  • Poor User Experience: When users click on a link, they expect it to work. A 404 error creates frustration and can cause them to leave your site, increasing your bounce rate.
  • Negative SEO Impact: Search engines like Google interpret broken links as a sign of a low-quality or poorly maintained website. This can lower your site's authority and rankings.
  • Wasted Crawl Budget: Search engine bots have a limited amount of time to crawl your site. If they are busy finding broken links, they may not index your important, working pages.

Frequently Asked Questions (FAQ)

1. How does this tool work without a server?

This tool uses a public CORS (Cross-Origin Resource Sharing) proxy to fetch the HTML of the URL you provide. It then extracts all links and attempts to "ping" each one through the proxy. Because it operates entirely within your browser, it's a clever but not foolproof method.

2. Are the results 100% accurate?

Due to the limitations of client-side checking, the results are highly indicative but not guaranteed. A link marked "Potentially Broken" is very likely a 404 or dead link. However, a "Seems OK" link could still be live but inaccessible to the proxy. Always double-check critical links manually.

3. Why is the scan slow on large pages?

The tool must make an individual network request for every single link found on the page. If a page has hundreds of links, this process can take several minutes. Please be patient while the scan completes.

4. Can it check an entire website?

No, this tool checks one page at a time. It does not crawl an entire website like professional desktop software (e.g., Screaming Frog). To check multiple pages, you must enter each URL individually.
