Nofollow Link Checker: Dofollow & Broken Link Highlighter

Highlight nofollow, dofollow, sponsored and ugc links on any page. Find broken links and redirects. Export all links to CSV.

Nofollow Link Checker shows you, in one click, which links on a page pass SEO value and which do not. Click the icon on any page to see: • Every link, labelled dofollow, nofollow, sponsored or ugc, read straight from its rel attribute • Internal and external links, counted and listed separately • Nofollow, sponsored and ugc links highlighted on the page in their own colours • Hover any highlighted link to see its rel value and full URL • A warning when the page's meta robots tag is nofollow or noindex, which overrides every link on it Broken link checker built in: • Click "Check broken links" to test every URL on the page • 404s and other dead links are struck through in red, redirects get an amber ring • Sites that refuse automated checks (401, 403, 429) are listed as Blocked, not as broken, so you only chase real problems Export: • Download all links as CSV with anchor text, rel, dofollow or nofollow, internal or external, HTTP status and final URL Who it is for: • Link builders checking whether a placement is dofollow before logging it • SEOs auditing outbound links, sponsored links and broken links • Editors and site owners cleaning up 404s Private by design. The extension reads the page only when you click the icon. It collects no data and sends nothing anywhere. The broken link check asks for permission the first time you use it, because it has to request each linked URL to read its status code. Free, no account.
