Checkers & Validators

Structured Data Validator

Validate JSON-LD structured data from a live URL or pasted markup, with schema.org type checks and required-property warnings.

Scope

This checks JSON-LD only — the format Google recommends and the one AI assistants parse most reliably. Microdata and RDFa are not analysed. It validates JSON syntax, @context, @type, and required and recommended properties for the common types.

What it does not do

  • It is not Google's Rich Results Test. Passing here means the markup is well formed and complete, not that a rich result is guaranteed.
  • It does not verify that your markup matches the visible page. That mismatch is a manual-action risk and no validator catches it.
