SEOquake is a free browser extension (by Semrush) that shows instant SEO metrics for any page you visit and even directly inside Google search results.

Quick Scoop

SEOquake works as a toolbar/overlay in browsers like Chrome and Firefox and is mainly used by SEOs, bloggers, and marketers to quickly evaluate how “strong” or optimized a page or SERP result is.

What is SEOquake?

  • A free SEO plugin/extension for Chrome, Firefox, and other major browsers.
  • It displays on-page and SERP-level SEO metrics without needing to open a separate tool.
  • Developed and maintained by Semrush, integrating some of their data into a lightweight browser tool.

Core things it can do

  • Show key SEO metrics at a glance (page info, indexation, basic authority metrics depending on your setup).
  • Run a quick SEO audit of a page (checks meta tags, headings, mobile friendliness, technical issues, etc.).
  • Analyze internal and external links on a page and export link data.
  • Check keyword density so you can see which terms are used most and avoid keyword stuffing.
  • Add an overlay to Google SERPs that shows metrics under each result and lets you export them to CSV.

Typical use cases

  1. Quick competitor check
    Open a competitor’s page, click the SEOquake icon, and see meta tags, headings, word count, and links to understand why it might rank well.
  1. SERP analysis before targeting a keyword
    Turn on the SERP overlay, search your target keyword, and see metrics for the top results to judge difficulty and opportunity.
  1. On-page content optimization
    Use the keyword density and diagnosis tools to refine titles, headings, and body content so they’re optimized but still readable.

Is SEOquake still relevant / “latest news”?

  • It’s still actively listed and updated in the Chrome Web Store as of early 2026, promoted as a “powerful SEO toolbox for your browser.”
  • Many beginner and intermediate SEO guides (published in 2024–2025) still recommend SEOquake as a quick, free way to do surface-level SEO checks without logging into a full SaaS platform.

Forum / discussion angle

When SEOs discuss “what is SEOquake” in forums and communities, they typically frame it as:

  • A fast, lightweight “first look” tool before doing deeper analysis in Semrush, Ahrefs, etc.
  • Handy for outreach, quick audits, and content reviews because it sits directly in the browser and can export SERP data.
  • Not a full replacement for dedicated rank-tracking, backlink analysis, or full technical crawlers, but an everyday helper.
