Broken Link Checker

Unsupported input

The tool may reject input that does not match the expected content, structure, or file type.

Fix: Confirm the tool input requirements and paste the correct type of data.

Incomplete values

Missing fields or partial content can block processing or produce weak results.

Fix: Provide the full required input before running the tool.

Copying placeholder content

Sample or placeholder values can lead to output that looks valid but is not ready for real use.

Fix: Replace placeholders with your actual values before relying on the result.

Does Broken Link Checker handle JavaScript-rendered pages?

Broken Link Checker fetches the raw HTML served to a crawler, which is what search engines index for the first pass. If your site relies on client-side rendering, the tool shows you exactly what Googlebot's initial render sees before it runs JavaScript.

What User-Agent does Broken Link Checker send?

Broken Link Checker sends a User-Agent string that identifies itself honestly (DevFox bot) rather than impersonating Googlebot — spoofing UAs can get a site's access flagged. If a page blocks non-browser UAs, you'll see the block clearly reflected in the output.

Can Broken Link Checker check password-protected pages?

No. Broken Link Checker only makes anonymous public requests — it can't log in or carry session cookies. For auth-protected pages, use a headless browser in your own environment.

Does Broken Link Checker respect my robots.txt?

Yes. Broken Link Checker fetches and parses robots.txt before crawling a site and skips disallowed URLs by default. You can toggle off the check if you're auditing your own site and want to see every status code.

How often is the data in Broken Link Checker refreshed?

Broken Link Checker fetches live data on every request — there's no cached result between sessions. That means you always see the current state of a page, at the cost of a small delay while requests complete.
