About Namespace SEO Studio
Namespace SEO Studio - Professional On-Page SEO Auditor
Stop guessing why your website isn't ranking. Namespace SEO Studio gives you an instant, professional-grade SEO audit for any webpage - right inside your browser, completely free.
Click the extension icon on any page and get a full audit in seconds. No accounts, no subscriptions, no data sent to any server. Everything runs locally in your browser.
What it analyses:
π Meta & SERP Optimization
Checks your title tag pixel width, meta description quality, canonical URL, robots directives, Open Graph tags, and Twitter Card - everything Google and social platforms read before your users do.
π Content & Semantics
Analyses word count, readability score, keyword density, heading hierarchy, semantic HTML structure, and content depth. Tells you exactly what's thin, what's stuffed, and what's missing.
βοΈ Technical & Crawlability
Verifies HTTPS, mixed content, viewport, HTML language, hreflang, structured data (JSON-LD), robots.txt, sitemap, DOM complexity, and third-party script load - the signals that determine whether Google can even access your page.
π Links & Structure
Audits your internal vs external link ratio, empty and generic anchor texts, anchor diversity, nofollow usage, and malformed URLs.
πΌοΈ Media & Accessibility
Checks alt text, lazy loading, image dimensions, inline base64 images, and accessibility signals like missing form labels and landmark roles.
β‘ Performance Heuristics
Flags excessive DOM nodes, render-blocking scripts and stylesheets, missing preconnect hints, and third-party domain overload.
