Analyse internal links: check 404s, 301 redirects, chains, loops, anchor text, dofollow/nofollow and highlight links on page. Internal Link SEO Checker is a free tool built for SEO specialists who want to quickly audit and fix internal links without switching between tools. Open the extension on any page and scan all internal links in one click. You'll instantly see which links return a 404, which are redirected (301), and where redirect chains or loops occur. Every link shows its anchor text, dofollow/nofollow attribute, and whether it was found in the HTML source or injected via JavaScript. Key features: - Status code checking: 200, 301, 404 per internal link - Redirect destination: see exactly where a 301 points to - Redirect chain detection: visualise multi-hop redirect paths - Redirect loop detection: catch A→B→A loops before they cause issues - Page highlighting: green/orange/red markers on all links (toggle on/off) - Scroll to link: jump directly to any link on the page - Smart copy: 301s copy the final URL, 404s copy the original - Search: filter by URL or anchor text - HTML / JS / HTML+JS: detect whether links are in source code or JavaScript - dofollow / nofollow: see rel attribute per link - Scan scope: choose which page elements to include (content, navigation, footer, sidebar and more) - Export CSV: all link data in one click, filename includes the scanned URL - Session cache: results persist if you accidentally close the popup - Sidebar mode: push the page aside and work with the tool next to your content v1.0.2 - Removed popup, sidebar only - Added stop scan button - Same URL count v1.0.1 - Search bar also matches full URLs, including domain names - Hover/scroll works for external links - Removed horizontal scrollbar in the sidebar - Restructured categories as described above
