Frequently Asked Questions

How does the broken link checker work?

It fetches the target page, extracts all anchor tags and their href attributes, then checks each link by sending a HEAD request. Links returning 4xx or 5xx status codes are flagged as broken.

Does it check internal and external links?

Yes. Both internal links (same domain) and external links (other domains) are checked. Results are categorized so you can see where problems are.

How many links can it check?

The tool checks all links found on a single page. For large pages with hundreds of links, the check may take a minute or two. Results appear progressively as each link is verified.

Why do broken links hurt my SEO?

Dead links waste crawl budget, send visitors to 404 pages, and signal a poorly maintained site to search engines. Fixing or removing 404s keeps link equity flowing and improves the experience for both users and crawlers.

Does it crawl my whole site or just one page?

It checks every link found on the single page you enter. To audit a whole site, run the checker on your key pages one at a time, starting with the homepage and high-traffic pages where broken links do the most damage.
