SEO Quake
SEOquake is a free browser extension that overlays on-page and SERP SEO metrics, including link data, keyword data, and basic diagnostics, for quick analysis.
Key takeaways
- SEOquake is a free, lightweight browser extension for instant SEO metrics.
- Use it for quick on-page checks, SERP analysis, and basic link profile overviews.
- LD = Linking Domains, not Link Density — avoid this common mistake.
- Not a replacement for dedicated SEO tools; use it as a complement.
- Ideal for beginners and quick audits, but limited for in-depth analysis.
It puts key metrics directly in your browser, saving time during competitive research and page-level audits.
What SEOquake is used for
- Quick on-page SEO audit: View meta tags, headings, alt attributes, and structured data.
- SERP overlay: See metrics like Google PageRank (deprecated), Alexa rank, and link data directly on search results.
- Link profile check: Instantly see L (total links) and LD (linking domains) for any page.
- Compare pages: Use the SEOquake toolbar to compare two URLs side by side.
- Export data: Download SERP results as CSV for offline analysis.
Quick start workflow
- Install SEOquake from the Chrome Web Store or your browser's add-on store.
- Click the SEOquake icon in your browser toolbar to activate the toolbar on any page.
- Use the toolbar to view on-page metrics (e.g., keyword density, link count, heading structure).
- For SERP analysis, perform a Google search and click the SEOquake icon to overlay metrics on results.
- Export data or compare pages using the toolbar options.
When not to start here
- For deep backlink analysis: SEOquake only shows L and LD; use Ahrefs or Semrush for full backlink profiles.
- For site-wide audits: SEOquake is per-page; use Screaming Frog or Sitebulb for crawl-based audits.
- For keyword research: SEOquake does not provide keyword difficulty or search volume; use Google Keyword Planner or Ubersuggest.
- If you need real-time data: SEOquake metrics are based on cached or historical data; for live data, use Google Search Console.
