Broken Link Checker: website SEO hygiene
Broken links are a silent killer of SEO and conversion. They signal low content quality to search engines and frustrate users. Regular broken link checking is a mandatory part of technical SEO auditing.
Full page link scan
Checks all links on the page — internal, external, images and resources.
Recognises JavaScript-rendered sites
Next.js, Nuxt, React, Vue, Angular, SvelteKit, Gatsby — their links are not in the source HTML, so an ordinary checker truthfully reports "0 broken links". We name the framework instead of passing an empty report off as a clean one.
Redirects
Detects redirect chains and links that technically work but point to the wrong destination.
Replacements for external 404s
External resources die, and deleting the link is not always the right answer. For dead external URLs we look up a saved copy in Archive.org and offer it as a replacement.

Frequently Asked Questions
What are broken links?
Broken links are links leading to non-existent pages (404), timeouts, or server errors. They worsen user experience, reduce SEO ranking, and waste search bot crawl budget.
How do broken links affect SEO?
Search engines view many 404 errors as a sign of an abandoned site. Broken internal links lose passed "weight" (link equity). Broken external links worsen user experience and may reduce behavioral metrics.
How often should links be checked?
Weekly checks are recommended for active sites, monthly for static ones. After content updates or migration, mandatory checking. Automated monitoring with notifications is the ideal option.
What to do with found broken links?
Options: fix the URL to a working one, set up a 301 redirect to a relevant page, remove the link if content no longer exists. For internal links, prioritize fixing. For external links, find an alternative resource.
What is the difference between 404 and 410?
404 (Not Found) means the page is not found but may return. 410 (Gone) means the page is permanently deleted. For SEO: 410 is removed from search index faster. Use 410 for content that will definitely not return.
What is crawl depth?
Crawl depth is the number of hops from the starting page to discover links. Depth 1 checks only links on the starting page. Depth 3 follows links three levels deep.
