Internal Link Checker

This SEO and navigation auditor crawls websites detecting broken internal links, redirect chains, or orphaned pages missing navigational pathways, essential for maintaining site health and optimal search engine crawling. The checker starts from specified URLs, follows all internal hyperlinks recursively, validates link destinations returning HTTP status codes, and identifies issues like 404 errors, 301/302 redirects, or inaccessible pages due to authentication requirements. Reporting categorizes problems by severity, lists specific source pages containing broken links, and provides fix recommendations like updating URLs or implementing permanent redirects. Visualization tools map site structure highlighting orphan pages accessible only via direct URLs, link equity analysis shows pages receiving most internal links indicating perceived importance, and comparison features track changes over time detecting newly broken links after site updates. Applications include pre-launch testing ensuring all navigation functions correctly, diagnosing traffic drops correlating with broken internal linking structures, maintaining large sites where content updates inevitably create orphan pages, or competitive analysis revealing rivals' site architecture and navigation strategies.
