Frequently asked questions
What does the Schema Checker validate?
It finds every JSON-LD block on the page, checks whether each one is valid JSON, lists the @types found, and gives per-type required-field hints.
Is this Google’s Rich Results Test?
No. This tool gives hints only — it is not Google’s Rich Results validator. Use it for a fast first pass, then confirm eligibility in Google’s own tools.
What is JSON-LD?
JSON-LD is the format most sites use to add structured data to a page: a small JSON block that tells search engines what the page is (an article, a product, an FAQ) in a machine-readable form.
Why does schema matter?
Structured data helps search engines understand a page’s content and can qualify it for rich results. Pages with valid schema are also easier for AI systems to parse and cite.
