Schema Inspector — SEO & LLM Readiness

Scan any page for schema.org markup: see the types, how they're implemented, and if Google & LLM crawlers can read them.

Schema Inspector audits the structured data on any web page with one click — and tells you whether Google and AI crawlers can actually read it. Open any page, click the icon, and get an instant report: 🔍 WHAT IT DETECTS Every schema.org type on the page — Article, Product, FAQPage, Organization, LocalBusiness, Recipe, Event, JobPosting, and more The implementation method: JSON-LD, Microdata, or RDFa Broken JSON-LD blocks with the exact parse error ⚡ JAVASCRIPT INJECTION DETECTION This is what makes Schema Inspector different. It fetches the page's raw HTML source and compares it against the rendered page. If your schema only exists after JavaScript runs (Google Tag Manager, React, a CMS plugin), it gets flagged — because while Google can render JavaScript, AI crawlers like GPTBot, ClaudeBot, and PerplexityBot don't execute it at all. JS-injected schema is invisible to them. ✅ CLEAR VERDICT WITH REASONS You don't just get raw data — you get a judgment: Good for Google & LLMs, Good with gaps, or Needs fixing. Every finding explains why it matters: Missing required and recommended properties, checked against Google's guidelines for 18 common types Deprecated rich result types (HowTo, restricted FAQ) that no longer earn snippets Duplicate entities that confuse parsers — often caused by a theme and a plugin both adding schema Missing Organization, WebSite, or Breadcrumb entities that help Knowledge Graph and brand attribution 🔒 PRIVATE BY DESIGN Everything runs locally in your browser. Nothing is collected, stored, or sent anywhere. The extension only activates on the tab you're viewing, when you click it. Perfect for SEO specialists, developers, content teams, and anyone preparing their site for AI-driven search.
