WHAT IT DOES When you're checking dozens of pages a day for client link opportunities, manually hunting for external links wastes hours. This extension does it in one click. It scans the page, highlights every link that points off-site, and gives you a clean breakdown of what's there. KEY FEATURES One-click highlighting: External links are marked directly on the page so you can see them instantly while reading. Hover tooltips: Hover any highlighted link to see its full URL, destination domain, and rel attribute (DoFollow, NoFollow, Sponsored, or UGC). Page overview stats: See total external links, number of unique domains, and internal link count at a glance. Links grouped by domain: The popup organizes all external links by their destination domain, so you know exactly which sites a page links out to and how many times. DoFollow vs NoFollow detection: Instantly identify which external links pass link equity, the single most important signal for guest posting and link building. Copy all URLs: Export every external URL to your clipboard with one click. CSV export: Download a full report (URL, domain, anchor text, rel attribute, link type) for client reporting or prospecting spreadsheets. Locate on page: Jump straight to any link's exact position on the page. Icon badge counter: See the external link count on the toolbar icon before you even open the popup. Auto-highlight mode: Optionally highlight external links automatically on every page you visit. Subdomain control: Choose whether subdomains count as external or internal.
