Finding dead links on a page
Enter a page URL and this tool fetches it, extracts every link, and checks each one's HTTP status to find broken links - 404s, server errors, or links that fail to connect at all. Broken links hurt both user experience and SEO (they waste crawl budget and can signal neglect), so catching them after a site migration, redesign, or content cleanup is worth doing regularly.
Why broken links actually hurt SEO, not just user experience
Search engine crawlers have a finite "crawl budget" for any given site - time and resources spent following dead links is time not spent discovering and re-indexing your actual working content. A page riddled with broken links can also read as a signal of a poorly maintained site, which plays into broader quality assessments search engines make.
Why checking after a migration or redesign matters most
URL structures frequently change during a site migration, CMS switch, or redesign - internal links written against the old URL structure silently become broken unless every single one was carefully updated or redirected. Running a broken-link check shortly after any major structural change catches exactly this class of problem before search engines or visitors discover it for you.
What the status codes actually mean
A 404 means the destination page simply doesn't exist at that URL anymore. A 500-series error usually means the destination server itself is having a problem, which might resolve on its own. "No response" typically means the request timed out or the domain itself is unreachable - worth a manual check, since it could be a temporary network issue rather than a genuinely dead link.
