About SEOquake: On-Page SEO Checker

SEOquake is a free on-page SEO checker extension for Chrome. Start with Quick View for a compact snapshot of the webpage you're viewing, then open Full Report when you need deeper analysis. Used SEOquake 3? SERP Overlay is back, country and language selection included, and it now covers AI Overviews. Diagnosis is now Audit in Full Report. Since 2006, SEOquake has helped website owners and marketers audit their own pages and study competitors without leaving the browser. What you can do ★ On-page SEO at a glance: Review the title tag, meta description, heading structure, canonical tag, indexability, and word count. ★ Page-level SEO audit: Find content, mobile, and technical SEO issues, with checks for robots directives, hreflang, XML sitemap availability, image alt text, and structured data. ★ SERP Overlay: Position numbers and Semrush metrics under each organic result on Google, in the country and language you choose. A free Semrush account adds Authority Score, visits, and engagement. ★ AI Overview sources: Research AI visibility right on Google. See which pages AI Overviews cite and compare sources using Semrush traffic and backlink metrics. ★ SEObar (SEO toolbar): Keep traffic estimates and backlink counts visible as you browse. Choose which metrics appear in SEObar, right on the page, without opening a separate report. ★ Internal and external link analysis: Find broken links and inspect URLs, anchor text, follow status, and HTTP status codes. ★ Keyword density report: See which words and phrases a page uses most, from single words to four-word phrases, and where they appear in the title tag, meta description, and H1. ★ Compare URLs and domains side by side: Benchmark your site against competitors using traffic estimates, backlinks, and other Semrush metrics in one view. ★ Built-in Semrush metrics: Get a quick read on a domain’s organic performance with Semrush Rank, estimated US organic traffic, Traffic Cost, and backlink data, completely free. Export the audit as a PDF, or download SERP, AI Overview source, keyword, link, and comparison data as CSV. Core reports and built-in Semrush metrics work without an account. Connect a free Semrush account to add Authority Score, referring domains and IPs, deeper backlink analysis, and Traffic Analytics, which shows how much traffic a site gets, where it comes from, and how visitors engage. Add the SEOquake extension to Chrome, open a webpage, and run your first SEO audit. Missing a feature from SEOquake 3, or found a bug?
