The broken link checker works like this: it crawls a page, extracts its links, then checks each destination's status code in polite batches. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.
How to use the Broken Link Checker
Enter the full URL, domain or content the tool asks for.
Run the check - fetch-based tools query the page server-side.
Read the findings as a list, not a single score.
Fix one issue at a time and re-run to verify.
Features
Checks run server-side so protected pages can be read
Results explain the rule or value behind every finding
Copy and export options for every result list
No account needed for any check
Common mistakes to avoid
Auditing a staging or password-protected URL instead of production
Fixing everything at once instead of one change plus re-test
Treating any single score as a ranking promise

Privacy
The URL you check is fetched once so the tool can read pages that block cross-origin browser requests. No browsing history is stored, and nothing from your own device is transmitted.
Frequently asked questions
Why do some sites show 403 for healthy links?
Some servers refuse automated requests to hot-linked pages while serving real browsers fine - treat those as "verify manually", not broken.
How does the checker treat redirects?
A redirect is followed and its final status reported - a chain ending at 200 is healthy; one ending at 404 or 410 is the broken link your users hit.
Why check in batches rather than all at once?
Polite pacing avoids hammering the destination servers and triggering blocks - the results arrive the same, just without abusing anyone's rate limits.
