Broken links quietly hurt both user experience and SEO — visitors hit dead ends, and search engines treat pages full of broken outbound links as lower quality.
This tool checks a batch of up to 20 URLs at once (one per line) and reports each one's HTTP status, flagging anything that comes back broken or unreachable.
How it works
Paste a list of URLs, one per line. The tool safely checks each one's hostname before contacting it, requests each URL independently, and reports whether it responded successfully or came back broken — one failing URL never stops the rest of the batch from being checked.
- Enter uRLs to check (one per line).
- Click Calculate to see your results.
Examples
Checking a mixed list
Given two URLs where one returns HTTP 200 and the other returns HTTP 404, the tool reports "1 of 2 URL(s) are broken" and lists exactly which one.
Who should use it
- Auditing a page's outbound links before publishing.
- Spot-checking a list of resource or citation links for a content refresh.
Industry applications
- SEO and content maintenance
- Web development and QA
Advantages
- Checks a whole batch of URLs at once instead of one at a time.
- One broken or unreachable URL never prevents the rest of the batch from being checked.
Limitations
- Capped at 20 URLs per check to keep the tool fast and responsive.
Common mistakes to avoid
- Only checking a site's homepage and assuming deeper pages are fine — broken links often live several levels into a site.
- Not re-checking links periodically — a link that worked when you added it can break later if the destination site changes.
Best practices
- Periodically re-check important outbound links (like resource pages or citations), since destination sites can restructure or go offline without any change on your end.
Tips
- If you find a broken link that used to work, check the Redirect Checker first — sometimes a "broken" link is really just an unexpected redirect chain rather than a genuinely dead page.
