Frequently asked questions

What is JSON-LD schema markup?

JSON-LD is the format Google recommends for structured data (Article, Product, FAQ, Recipe...) that unlocks rich results in search.

Does it validate my schema?

It validates JSON syntax and reformats it. For full Schema.org type validation, test in Google's Rich Results tool after formatting.

Is my markup uploaded?

No. Formatting and validation run 100% in your browser. Your structured data stays private.
