Does passing validation guarantee a rich result?

No. Validation confirms the syntax is correct and required properties are present. Whether Google shows a rich result also depends on content quality, overall site standing, and whether that result type is enabled in your region. Any tool claiming otherwise is being dishonest.

JSON-LD, Microdata, or RDFa?

Google explicitly recommends JSON-LD. It sits separately from the HTML structure inside a ` ` block, so editing markup never disturbs the layout, which makes it the cheapest to maintain. This tool produces JSON-LD only.

About this tool

Choose a type, fill the fields, and get schema.org JSON-LD ready to paste. You can also paste existing JSON-LD to validate: whether the JSON parses, whether `@context` points at schema.org, whether `@type` is present, and whether the required properties for that type are filled — walking into `@graph` to check every node. Worth stating plainly: complete properties mean valid markup, not a guaranteed rich result, which also depends on content quality and Google's own judgement.

How it works

Choose a schema type such as Article or Product.
Fill in the required and optional properties.
Copy the JSON-LD, or switch to validation and paste existing markup.

Limits and notes

Checks @context, @type, and each type's required properties. Passing does not mean Google will show a rich result.

Privacy

Pasted HTML, URLs, and text are analysed inside this browser only. Nothing is uploaded, stored, or written to the URL or any log.
