About Schema Markup Validator

Schema Markup Validator is the Schema.org project's tool for checking structured data. You run a test against a URL or pasted code, and it extracts the Schema.org markup it finds and reports syntax problems.

Unlike search engine tools that focus on eligibility for particular rich results, it validates against the Schema.org vocabulary in general. The interface is available in many languages. It suits developers and SEO specialists adding structured data to pages.

Strengths

  • Official validator from the Schema.org project
  • Checks a live URL or a pasted snippet
  • Interface in many languages

Limitations

  • Does not tell you whether a page qualifies for specific search rich results
