Broken Link Checker

Free Broken Link Checker — Scan Your Entire Site for Dead Links

Broken links quietly damage user experience and SEO — every 404 a visitor hits is a chance they leave, and every dead link Google crawls chips away at your site's authority. Our free broken link checker reads a site's sitemap.xml, crawls its internal pages, and checks every internal and external link it finds, reporting exactly which URLs return 4xx or 5xx errors. No installs, no accounts, just paste a domain and watch the results stream in live.

Why Broken Links Hurt Your Site

Search engines and users both judge a site by how well it's maintained. Dead links waste crawl budget, break internal linking structure, and create dead-end user journeys that increase bounce rate.

• •Lost SEO equity — links pointing to 404 pages pass no value and waste crawl budget
• •Poor user experience — visitors hitting dead ends are more likely to leave without converting
• •Damaged credibility — broken links make a site look outdated or neglected
• •Missed conversions — a broken link on a checkout or CTA path directly costs revenue

How the Scan Works

The checker starts by reading /sitemap.xml (following nested sitemap indexes), then crawls internal pages to discover additional links that may not be listed in the sitemap. Every internal page and every external link referenced from those pages is checked for a live HTTP status, with results streaming to the screen as they complete.

• •Automatic sitemap.xml and sitemap index discovery
• •Full internal page crawl to catch links missing from the sitemap
• •Checks both internal pages and outbound external links
• •Live, real-time results list as the scan progresses
• •Flags 4xx and 5xx responses, plus unreachable/timeout errors, as broken
• •One-click CSV export of the full report for sharing or tracking fixes

Built for Developers, SEOs & Site Owners

Run a scan before a launch, after a migration, or as part of routine site maintenance to catch dead links early. Agencies can use it to audit client sites quickly, and site owners can export the CSV report to hand off to a developer for fixes — all without installing crawling software or paying for a subscription tool.
