Some websites block browser-based requests or do not allow cross-origin checking. In those cases, the result is shown as "Could Not Verify" rather than incorrectly marking the URL as broken.

What Is a Broken Link?

A broken link is a URL that does not successfully lead to the intended webpage or resource. The destination may have been removed, moved, renamed, restricted, or become temporarily unavailable.

Broken links can appear on websites, blogs, documentation pages, resource lists, navigation menus, and other online content. Regular link checking can help identify URLs that need review.

How to Use the Broken Link Checker

1. Copy the URLs you want to test.
2. Paste them into the URL field, using one URL per line.
3. Select Check Links.
4. Review the response and status shown for each URL.
5. Investigate links marked as broken or unable to be verified.

Understanding Link Statuses

Working

A working result indicates that the browser was able to receive a successful response from the destination.

Broken

A broken result indicates that the destination returned an HTTP error response or otherwise failed the availability check.

Could Not Verify

This result commonly occurs when the destination blocks browser requests, restricts cross-origin access, requires authentication, or otherwise prevents the browser from reading its response.

Invalid

An invalid result means the entered value could not be interpreted as a valid web URL.

Common HTTP Errors

404 Not Found — The requested resource could not be found.

403 Forbidden — The server refused access to the requested resource.

410 Gone — The resource has been permanently removed.

500 Internal Server Error — The server encountered an internal error.

503 Service Unavailable — The server is temporarily unable to handle the request.

Why Check for Broken Links?

• Find outdated URLs on a website.
• Identify links that may need replacement.
• Maintain useful navigation and resources.
• Review links after moving or deleting pages.
• Reduce the number of inaccessible destinations in your content.

Common Causes of Broken Links

• A webpage has been deleted.
• A page URL has changed.
• A domain has expired or changed.
• A URL was typed incorrectly.
• A linked resource has been moved.
• A website has temporarily gone offline.
• A server blocks automated or browser-based requests.

Tips for Maintaining Website Links

Check important links after major website changes, migrations, domain changes, or content reorganizations. Pay particular attention to navigation, important resources, external references, and pages that receive significant traffic.

When replacing a broken URL, confirm that the new destination actually provides the information or resource expected by visitors instead of simply choosing another available page.

Frequently Asked Questions

What is a broken link checker?

A broken link checker is a tool used to test URLs and identify destinations that appear unavailable, return errors, or cannot be verified.

How do I check if a link is broken?

Enter the URL into the checker and run the test. The result can indicate whether the browser received a successful response, an HTTP error, or could not verify the destination.

Why does a working website show as unable to verify?

Some websites block cross-origin browser requests or restrict access to their responses. The destination may still work normally when opened directly.

What does a 404 error mean?

A 404 response means the server could not find the requested resource at that URL.

Can a broken link become a working link later?

Yes. Temporary server problems, network issues, or service interruptions can cause a link to fail temporarily.

Can I check multiple links at once?

Yes. Enter multiple URLs with one complete URL on each line and the checker will process them individually.

Does a browser-based checker detect every broken link?

No. Browser security policies and server restrictions can prevent some URLs from being verified directly.
