Ahrefs SEO Toolbar

Ahrefs SEO Toolbar packs on-page checks, keyword research and link analysis into one Chrome extension. In search results you can switch regions, Google domains and languages and pick up new keyword ideas without a VPN. On any page, one click checks titles, meta descriptions, headers and technical factors such as canonical tags and indexation directives. It highlights links, traces redirects, switches user agents to see a page as Googlebot, reads HTTP headers and returns page speed data. Domain and page metrics such as keyword counts, traffic estimates and referring domains appear directly on every domain or result. The toolbar itself is free, though an Ahrefs subscription is required to see the Ahrefs metrics, which suits SEOs who live in search results.
