Free Broken Link Checker: Find Dead Links Before Google Does

A boutique law firm we work with had a practice-area page that had ranked steadily for two years, then dropped from position 4 to position 14 over one quarter. Nothing in the copy had changed. We cross-referenced the page against Search Console’s crawl stats and found the issue in the citations section: two outbound links returning hard 404s, and one redirecting through a three-hop chain to a resold, unrelated domain. Google’s own crawling documentation says plainly that broken links are dead ends for crawlers and waste the crawl budget allotted to a site. We fixed the three links, resubmitted the page, and it recovered to position 6 within five weeks. That’s the exact audit step this tool automates.

What This Tool Does, and How It Actually Works

Paste in a URL or a full domain. The tool sends a request to every outbound and internal link it finds, using a lightweight HEAD request first and falling back to a full GET if the server doesn’t support it, then reads the response code. Anything landing on a 404, a 5xx error, or a redirect chain past two hops gets flagged, along with the exact page it was found on. Requests that don’t resolve within a short timeout are marked separately from confirmed dead links, since a slow server isn’t the same problem as a missing page. As a free broken link checker, it replaces the manual click-through audit most smaller agencies still do by hand, one link at a time.

Where SEO Teams Use This Day to Day

• Auditing a client’s site before a content refresh or migration
• Checking outbound links on older blog posts that haven’t been touched in a year or more
• Verifying internal links after a site restructure or URL change
• Reviewing a guest post draft before publishing to confirm every reference link resolves
• Running a quick health check on a newly acquired domain before building on it

How to Run a Scan

1. Enter the URL or domain you want checked.
2. The tool crawls the page or site and tests every link it finds.
3. Results come back grouped by status: working, broken, redirected, or timed out.
4. Each broken link is listed with the page it appeared on, so you know exactly where to fix it.
5. Re-run the scan after fixes to confirm everything resolves cleanly.

Where This Tool Has Limits

The checker tests links as they exist at scan time, so it can’t catch a link that breaks an hour later, that needs ongoing monitoring, not a single scan. Pages blocked by robots.txt or requiring a login won’t be reachable. A “soft 404,” a page that returns a 200 status but shows no real content, can sometimes pass as working; Google’s own troubleshooting documentation flags this exact pattern as a common source of wasted crawl budget. Treat this tool as a strong first pass, not a substitute for manually spot-checking your highest-value pages.

Why Agencies Trust This Tool

I’ve led technical SEO audits for enterprise and mid-market clients for over nine years, and we run a link check like this one on roughly 40 client audits a year, it’s one of the first things we look at because it’s cheap to fix and easy to miss. This tool runs the same request-and-response logic we’d run manually, reviewed personally each quarter against Google’s published crawl error guidance.

We don’t retain scanned URLs or crawl results after a report generates, each scan runs fresh and isn’t stored against your account. If a result looks miscategorized, our support team will look into it, this is a rule-based tool, not a black box.

Frequently Asked Questions

How is this different from other broken link checker tools?

Many tools only check outbound links. This one flags internal and outbound broken links, plus timeouts, in the same scan, which matters most for large content libraries.

Will this slow down my site?

No, the scan runs from our servers and doesn’t add load to your own hosting beyond normal crawl requests.

Is this online broken link checker really free?

Yes, no signup or cost required to run a scan.Stop losing rankings to links that quietly stopped working. Run a free scan now and fix what’s broken before it costs you traffic.
