Why Broken Links Hurt Your SEO
Search engines follow links to crawl your site. A broken link is a dead end — it wastes crawl budget, frustrates visitors, and signals to Google that your content is poorly maintained.
Crawl Budget Waste
Googlebot has limited crawl budget per site. Broken links eat into it without delivering any indexed page, slowing discovery of new content.
User Experience
A 404 page is a dead end for users. High bounce rates from broken links signal low quality to search engines and damage conversion rates.
- Internal broken links stop crawlers from reaching important pages
- External broken links erode trust with readers and search engines
- Redirect chains slow page loads and dilute link equity

Frequently Asked Questions
What is a broken link?
A broken link is a hyperlink that points to a page or resource that no longer exists or is unreachable. They return 4xx or 5xx HTTP status codes and hurt both user experience and SEO.
How many links does this tool check?
This tool checks the first 100 unique links found on the page, several at a time. Each link gets a HEAD request, with a GET fallback for servers that reject HEAD, and up to 8 seconds to answer. Some sites block automated checks (shown as bot-blocked) or respond slowly, so re-check any flagged link in your browser before fixing it.
Do broken links hurt SEO?
Yes. Broken links waste crawl budget, create poor user experiences, and can signal low content quality to search engines. Internal broken links are especially harmful as they interrupt crawl paths.
What is the difference between a broken and a redirected link?
Broken links return 4xx or 5xx errors — the destination is missing or broken. Redirected links return 3xx codes — the URL has moved. Redirects are usually fine but add latency and can lose link equity if not using 301s.
Does this tool modify my website?
No. It only reads your page and sends HEAD (or header-only GET) requests to the links it finds. Nothing is written or changed on your site.
