Ahrefs SEO Toolbar
Browser ExtensionAhrefs metrics and on-page SEO audit in your browser
Overview
Ahrefs SEO Toolbar brings the company's domain metrics and technical SEO analysis directly into your browser as a free extension. Released in 2019, it serves as a lightweight companion to the main Ahrefs platform, offering immediate access to Domain Rating, URL Rating, and backlink counts for any page you visit. Unlike paid browser extensions from competitors, the toolbar provides substantial functionality without requiring an Ahrefs subscription.
The extension focuses on three core areas: displaying Ahrefs' proprietary metrics, running on-page SEO audits, and identifying technical issues like broken links and redirect chains. It's essentially a mobile version of Ahrefs' Site Explorer and Site Audit tools, optimized for quick analysis during regular browsing sessions.
The toolbar stands out from alternatives like MozBar or SEOquake by leveraging Ahrefs' extensive backlink database—the same data that powers their $99+/month platform. This gives users access to some of the industry's most comprehensive link metrics without any cost barrier.
