A broken link is a hyperlink that no longer points to a live page — typically returning a 404 Not Found, 410 Gone, or server error (5xx). Broken links harm user experience, waste crawl budget, and can lower search rankings. How does the site crawler work? In Full Site Crawl mode, the tool starts at your homepage, extracts every link, then crawls each internal page it finds — up to 20 pages and 150 unique links total. External links are checked for status but not crawled further. Does it check external links too? Yes. Both internal and external links are checked for their HTTP status code. External links are labelled separately so you can prioritise fixes that affect your own pages first. What do the status codes mean? 200 OK = working. 301/302 = redirected (may need updating to direct links). 404 = page not found (broken). 410 = deliberately removed. 5xx = server error on the destination. 0 / timeout = the destination is unreachable or too slow. How often should I run a broken link check? Monthly is the recommended cadence for most websites. Run it after any site migration, URL restructure, or major content deletion. A clean link profile is a continuous hygiene practice, not a one-time fix.

A broken link is a hyperlink pointing to a page that no longer exists, returning a 404 Not Found or similar error. Broken links hurt SEO by wasting crawl budget, signalling poor site maintenance to Google, and delivering a bad user experience that increases bounce rate. ### How does the broken link checker crawl a website? In Full Site Crawl mode, the tool starts from your homepage, extracts all links, then follows internal links to crawl up to 20 pages. For every link discovered — both internal and external — it makes an HTTP HEAD request to determine the status code. Results stream in real-time as each link is checked. ### What status codes does the tool detect? The tool detects 200 OK (working), 301/302 redirects, 403 Forbidden, 404 Not Found, 410 Gone, 429 Too Many Requests, 500/502/503/504 server errors, connection timeouts, and unreachable domains. Each is colour-coded for quick triage. ### Is there a limit on how many links are checked? The free tool checks up to 150 unique links across up to 20 crawled pages. This covers the majority of small-to-medium websites. For enterprise-scale audits across thousands of pages, our SEO team offers a full technical audit service. ### How often should I run a broken link check? Run a broken link check monthly as a minimum. Also run it after any site migration, URL restructure, content deletion, or CMS update. Catching broken links early prevents them from accumulating into a significant SEO liability.
