Schema Checker

The Schema Checker is a free audit of your site's structured data (JSON-LD) health. Audits the JSON-LD schema on your site: finds missing or broken types (Organization, Product, FAQPage, Article, Breadcrumb) and explains how to add each one.

What does this tool do?

What it is: Audits the structured data (JSON-LD schemas) on your page, flags missing and broken types, and explains how to add each missing type.

Why it matters: Schema is the clearest answer machines trust for "who is this page and what is it about"; when it is missing or broken, AI engines read your content by guesswork.

What it looks at: Schema types like Organization, FAQ, Article and Product; required and recommended fields; broken blocks; a platform-aware guide for adding each missing type.

Why does AI visibility matter now?

  • 87.4% of AI referral traffic comes from ChatGPT, and those visitors convert at twice the rate of traditional sources (Conductor, 2026).
  • AI Overviews cut classic organic clicks by 34.5% (Ahrefs, 2025).
  • Princeton research shows that adding sources, statistics and quotations to content boosts visibility in AI answers by up to 40% (arXiv, 2023).
If AI isn't recommending you, it's recommending a rival.
