Schema Markup Checker

Schema Markup Checker

See what schema markup a page contains, whether the JSON-LD can be read, and what needs your attention before you open the official validators.

  1. Find every JSON-LD block and the Schema.org types inside it.
  2. Catch broken JSON, missing types, weak identifiers, and canonical disagreements.
  3. Leave with the right next check instead of guessing which validator to use.

Check a page or paste the code

Know what the result means

This checker finds JSON-LD blocks, reads their types and identifiers, and flags common block-level problems. It does not decide whether Google will show a rich result or whether an AI system will use the markup.

Learn schema markup from the beginning, then use the Google Rich Results Test and Schema.org Markup Validator for their official checks.
