Free Broken Link Checker

A broken link is a destination URL that no longer resolves. The most common codes are 404 Not Found (page deleted or moved without a redirect), 410 Gone (page permanently removed), and 500 Internal Server Error (server failure on a real page). All three tell Google the link target is unusable, and all three cost you. The crawler hits a 404 and learns that the path is dead; the user clicks a 404 and bounces; the page that pointed to the 404 passes less PageRank than it would have passed to a live destination.Google has been clear for years that a small number of 404s is normal and does not directly hurt rankings. The damage shows up in crawl budget. Every broken link is a path the crawler wastes time on, and on a 10,000-page site with 200 broken links the cumulative cost adds up. Worse, broken internal links to old product pages or migrated URLs break the link equity flow you spent months building.Our crawler starts at any homepage and walks every same-origin internal link up to 3 levels deep, up to 100 pages per run. It checks the HTTP status of every destination it discovers and reports the broken ones with their source URL and the anchor text a user clicked. You get a fix list, not a graph: source page, broken destination, status code, anchor. Patch them with 301 redirects or by replacing the destination, and your crawl budget recovers.
