Schema Markup Generator
Generate editable JSON-LD from factual properties for supported schema types. Copy and validate before publishing.
What this tool does
Create a JSON-LD object with a selected schema type and properties you supply. Context and type are set by the generator, while all other factual properties come from your JSON input.
How to use it
Choose the type matching visible content. Enter valid JSON properties. Generate and copy the output. Validate vocabulary and consumer-specific requirements before adding it to the page.
Why it matters
Explicit structured descriptions can reduce ambiguity. Markup must represent the visible page honestly.
Example
An Organization object can include its real name, canonical URL and supported sameAs profiles. An Event needs appropriate dates and venue information, not invented values.
Understanding the result
The output is well-formed JSON-LD syntax. The tool does not fill missing required fields or certify eligibility.
Limitations
This is a flexible generator, not a complete vocabulary validator. FAQ and HowTo markup do not guarantee a Google rich result. Never invent reviews, authors or ratings.
Frequently asked questions
Does this guarantee search visibility?
No. This tool reviews the supplied evidence. Search engines and AI systems make independent selection decisions.
Is my input stored?
Browser tools process locally. Server tools process the input; reports are saved only when requested. Connected AI and data tools send required input to their service providers.
