1. Ahrefs SEO Toolbar
SERP metrics and on-page report from Ahrefs data.
Why it replaces SEOquake: Better data quality on backlinks and traffic if you already pay for Ahrefs, with a cleaner SERP overlay.
SEOquake is a strong option, but it is not the right fit for everyone. Below are 4 alternatives compared on rating, install base, pricing and the use case each one actually wins on.
SEOquake is the broadest free SEO toolbar available. It overlays a configurable bar of metrics on search results and any page you visit, runs an on-page SEO audit, checks internal and external links, compares domains side by side, and exports SERP data to CSV — all without a paid subscription, though Semrush data is richer when you are signed in. The strength is breadth: keyword density analysis, a page audit against common on-page rules, a link inspector and a domain comparison tool sit in one extension rather than four. The cost of that breadth is a busy interface, and default settings that put more numbers on screen than most people need. Ten minutes in its parameter settings, cutting the bar to the four metrics you actually use, changes the experience completely. As with every toolbar, the traffic and keyword volumes are modelled estimates from Semrush's dataset. Use them to compare pages and queries against each other, and confirm anything you plan to act on for your own site in Search Console.
