Free broken link checker
Scan a page for broken links — the dead 404s and server errors that frustrate visitors and quietly erode SEO. Paste a URL and we'll check its links right now.
What this checks
We extract the links on the page, request each one, and flag any returning a 4xx or 5xx status. Mailto/tel/anchor links are skipped and the crawl is capped, so it's fast and polite.
Why broken links matter
They waste crawl budget, hurt user experience, and signal neglect. A few won't sink a site, but they accumulate as pages move and external sites disappear.
Keep client sites clean
Sitefolio re-checks links on a schedule and alerts you when new ones break — so you catch them before your client does.
