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. ★ SEObar: 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, 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?
