Broken link checker
Put in a page URL. The tool pulls out the links and checks each one, then lists the broken ones first with their status codes.
Fetched live, exactly as a crawler receives it.
Why broken links matter
A broken link wastes a crawl and sends people nowhere. Internal broken links are the bigger problem, because they usually mean a section of the site is unreachable.
What to fix first
- Internal links returning 404 or 410: fix the href or restore the target. Highest value.
- Internal links that 301: update the href to the final URL and save every visitor a hop.
- External 404s: replace with a live source or an archive.org snapshot, or unlink.
- Status 0 targets: DNS failures, timeouts or refused connections. Usually dead domains.
The tool checks up to 25 links per run so it stays quick and does not hammer the sites it is checking. Run it on your important pages rather than trying to do the whole site at once.
