What Is a Broken Link?
A broken link is one whose destination can't be reached successfully, most often because the page has been removed, moved without a redirect, or the destination server can't be reached at all. Not every non-200 response is broken in the same sense, a redirect points somewhere new on purpose, and an access restriction means the resource may still exist but isn't reachable by an automated checker.
How a Broken Link Checker Works
- Fetch the source page you submitted.
- Extract the links found in its HTML.
- Resolve every relative, root-relative, and protocol-relative link into a full URL.
- Check each unique destination for reachability.
- Classify each response into a clear category.
- Report the results, with a factual summary and filterable detail.
What Is a 404 Error?
A 404 means the server was successfully reached, but has no page at the requested address. It's the most common and clearest form of a genuinely broken link, and this checker reports it as Broken.
What Does a 301 Redirect Mean?
A 301 (or 302) tells a browser the content has moved to a different URL, and it should go there instead. This checker follows redirects safely and reports both the original and final URL, a redirect isn't treated as broken, though a long chain of them is worth cleaning up over time.
Are 403 Links Broken?
Not necessarily. A 403 means the server refused the request, often because it requires authentication, expects a specific referrer, or deliberately blocks automated tools like this checker. The resource may work perfectly for a real visitor in a browser, this checker labels it Restricted rather than Broken to reflect that real difference.
Why Fix Broken Links?
Broken links interrupt a visitor's path through your site and can quietly signal a page that hasn't been maintained. Fixing them cleans up navigation and improves the experience for anyone following a link expecting it to work. Broken links aren't automatically a direct ranking penalty, but a page with many of them, or one that's clearly gone stale, is a real maintenance issue worth addressing on its own merits.
Internal vs External Broken Links
An internal broken link points back to the same site and is usually within your control to fix directly. An external broken link points to a different site, whose content or availability you don't control, so the right fix is often to update the link to a current source or remove it rather than expect the original to come back.
How to Fix Broken Links
- Correct a simple typo in the URL.
- Update the link to the resource's current location.
- Replace an obsolete external link with a current, relevant source.
- Add a redirect from the old URL if it still receives traffic.
- Remove the link entirely if it's no longer relevant to the page.
Broken Links vs Redirects
A broken link goes nowhere useful. A redirect deliberately sends a visitor from one URL to another, and when set up correctly it preserves the experience of following the original link. The two are reported as separate categories here because they call for different action, a broken link usually needs a direct fix, while a redirect is often working exactly as intended.
Limitations of Online Broken Link Checkers
- Links added to a page only after JavaScript runs in a browser aren't detected.
- Links behind a login or other authentication can't be checked as this tool.
- Some sites block automated requests, which can look like a restriction rather than a real broken link.
- Rate limits, on this tool or on the destination site, can affect how many links are checked in one scan.
- A temporary server error at the moment of checking may not reflect the link's normal, working state.
