Structured Data Validator

Paste JSON-LD or a whole head — or give us a URL and we fetch it — and find the shape errors that void the markup.

Paste JSON-LD, or HTML containing it

Paste mode is offline: nothing is uploaded and nothing is fetched. This checks shape, not rich-result eligibility. Whether a page wins a rich result depends on Google's current requirements for that result type; only Google's own testing tools can answer that.

Paste JSON-LD on the left and the findings appear here.
