What is SEO Spider?

broken link checker (Screaming Frog SEO Spider) scans websites to find broken links and HTTP 404/4xx errors. It crawls sites in spider or list mode, reports response codes, and identifies internal and external broken links. The Inlinks view shows source pages, anchor text, alt text and follow/nofollow attributes to pinpoint where broken links originate. Bulk export and reports (Client Error 4xx inlinks, redirects) let users trace redirect chains and extract source-to-broken-URL mappings. Advanced settings include configurable crawl depth and crawl-fragment support to detect broken jump links and named anchors. Outputs support SEOs, webmasters, developers, and content managers for technical SEO audits, link maintenance, and content remediation. Use the crawl overview and issues tab to prioritize high-priority internal errors and lower-priority external link warnings for remediation workflows.
