Schema Markup Checker — Free

Check if your website has valid Schema.org JSON-LD structured data. Part of our free 8-signal AI-readiness scan.

What Is Schema.org Markup?

Schema.org is a vocabulary of tags (microdata and JSON-LD) that you add to your HTML to help search engines and AI models understand the content on your pages. It's a collaborative project by Google, Microsoft, Yahoo, and Yandex.

For AI models specifically, schema markup is critical because it provides unambiguous, machine-readable context about what type of entity your page represents. Without it, LLMs must infer meaning from raw text — which leads to errors and missed recommendations.
