About Schema Inspector — SEO & LLM Readiness
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.
