About Broken Link Checker

Enter any URL and instantly scan every link on the page — internal, external, images, CSS and JavaScript files. For each link the checker reports the HTTP status code, response time, redirect target and anchor text. An overall SEO Health Score (0–100) measures the impact of broken links on your site's crawlability and user experience. Broken internal links, redirect chains, missing images, broken CSS and broken JavaScript are each flagged with specific recommendations. Export the full report as CSV, JSON, TXT or a print-ready PDF.

Frequently Asked Questions

A broken link (dead link) is a hyperlink that points to a resource that no longer exists or is temporarily unavailable — returning an HTTP error like 404 Not Found, 410 Gone, 500 Server Error or a timeout. Broken links degrade user experience, waste crawl budget and can signal low site quality to search engines.

Broken internal links waste Google's crawl budget and prevent link equity from flowing to important pages. They signal neglect and low site quality. Broken links also increase bounce rate when users click them and hit an error page, reducing dwell time and engagement metrics. Google's John Mueller has confirmed that too many broken links can negatively affect how a site is perceived by the crawler.

Yes. The checker tests every link found on your page by default, including links to third-party websites. External links can break when the destination website changes its URL structure, removes pages or goes offline. Enable 'Include External Links' to include these in your scan.

For active websites, run a broken link check monthly or after any major content migration, CMS upgrade or URL restructure. E-commerce sites should check more frequently since product pages are added and removed regularly. News and blog sites should check quarterly at minimum.
