Nofollow Highlighter – SEO link marker

Description

Highlights nofollow, sponsored, ugc and dofollow links on any page. An SEO tool that runs locally and sends no data. Nofollow Highlighter instantly shows how every link on a page is treated for SEO, based on its rel attribute — so you can audit internal and outbound links at a glance. Each link is color-coded by type: • dofollow (green) — passes link equity • nofollow (red) — does not pass equity • sponsored (orange) — paid / advertising link • ugc (blue) — user-generated content (comments, forums) Links with several rel values (e.g. rel="sponsored nofollow") are classified by priority: sponsored → ugc → nofollow. Hover any link to see its full rel value and whether it points to an internal or external domain. KEY FEATURES • Automatic highlighting on the pages you visit — no clicking required • Toolbar badge with the number of non-dofollow links on the current page • Choose which link types to highlight (e.g. only nofollow, or nofollow + ugc) • "External links only" mode for outbound-link audits • Three marking styles: underline, badge, or both • Global on/off switch and a per-site toggle (exclude specific domains) • Live updates — changes apply instantly, no page reload needed • Works with dynamically loaded content (infinite scroll, single-page apps) PRIVACY FIRST This extension runs 100% locally. It only reads the page you are on to color its links. It makes no network requests, collects no data, uses no tracking, and loads no remote code. Nothing ever leaves your browser. Only http/https links are marked; anchors (#), mailto:, tel: and javascript: links are skipped. Perfect for SEO specialists, content editors, link builders and webmasters who need a quick, trustworthy view of a page's link profile.
