Schema Markup Validator

Structured data validators

FreeSEO, growth & newslettervalidator.schema.org

What it is

The Schema Markup Validator checks JSON-LD, Microdata or RDFa against schema.org vocabulary, while Google's Rich Results Test checks whether that markup qualifies for a specific rich result. Search Console then reports structured data errors across every indexed page.

Why it earns a slot

For a content site, NewsArticle, Person and FAQPage markup drives rich results and hands AI crawlers clean facts to lift. Validating before publish stops a broken template shipping across the whole archive.

Know before you commit

Valid markup does not guarantee rich results — Google decides. The generic validator happily accepts schema Google ignores, so run both tools.

Getting started

Paste your rendered JSON-LD into validator.schema.org.
