Schema Markup Validator

Check your structured data JSON-LD for errors, warnings, and missing fields before publishing it to your site.

Validate Your Schema

Paste your JSON-LD script below to check for syntax errors and schema compliance.

What is this?

The Schema Markup Validator allows you to test your JSON-LD code snippets to ensure they follow Schema.org guidelines and are correctly formatted before you deploy them.

Broken or invalid schema can lead to search engines ignoring your structured data entirely, costing you valuable rich snippets in search results. This tool acts as your first line of defense against syntax errors and missing requirements.
