How the Broken Links Tester scans your website

The scanner starts at your URL, extracts every internal and external link on the page, and for larger sites follows the internal page graph within a defined scan scope. Each discovered link is requested via HEAD (falling back to GET) and classified by HTTP status. The result separates hard errors (4xx/5xx) from warnings (3xx chains, slow responses, protocol mismatches) so you can focus fixes where they matter.

Hard errors (4xx)

404 Not Found, 410 Gone, 403 Forbidden, 401 Unauthorized — immediately visible to users and crawlers. Highest priority for fixing.

Server errors (5xx)

500 Internal Server Error, 502/503/504 gateway errors, connection timeouts. Often intermittent, always hurt crawl budget and UX.

Redirect chains

301/302 redirects are fine — unless they chain. 3+ hops cost crawl budget and link equity. The scanner flags chains and their length.

External link health

Outbound references to third-party resources that disappeared, moved, or are now parked. Erodes credibility on long-lived content.

Mixed-content warnings

HTTP links on HTTPS pages trigger browser warnings and break SSL trust signals. The scanner flags every HTTP link.

Slow targets

Destinations that take > 3s to respond. Frustrates users, bleeds ad-click value, and weakens perceived site quality for Google.

The public result shows broken-link count, warning count, and the top 3 affected source pages so you know immediately if your site has a problem. The detailed PDF report delivered after double opt-in lists every broken link with source page, anchor text, HTTP status, and a concrete fix recommendation — typically 50–200 entries on a mid-sized site, ordered by traffic impact.

FAQ: Broken links checker

How can I find broken links on my website?

Enter your domain in the Broken Links Tester and get an instant list of broken internal and external links.

Do broken links affect SEO?

Yes. Broken links hurt crawl quality and user experience, which can reduce rankings and conversion performance.

What should I fix first after the scan?

Start with high-traffic pages, remove dead targets, replace broken references, and add clean redirects where needed.

How deep does the Broken Links Tester crawl?

It follows internal links within the domain up to a defined depth and checks every external reference once via HTTP status.

Which HTTP status codes are treated as errors?

4xx codes (e.g. 404, 410) are treated as broken, 5xx as server errors. 3xx redirects are flagged as warnings when they form chains.

How often should I check for broken links?

Monthly is a good cadence for active sites. After major content changes or migrations, also run an ad-hoc check.

Does every broken link hurt my SEO?

Internal broken links and links on important pages matter most. Isolated dead external links on niche pages are less critical.

Are 301 redirects detected?

Yes. Short 301 redirects pass as OK, while long redirect chains are flagged as warnings and should be shortened.

Do I get the report as a file?

Yes. After newsletter confirmation you receive a PDF report with a prioritized link list, source pages, and fix recommendations.
