What is JSON-LD Starter Builder?
JSON-LD is structured data written as a script block in the page head or body. It helps search engines and AI systems understand entities, page purpose, navigation paths, and question-answer content. This builder focuses on starter markup that is easy to inspect and adapt before publishing.

limitations
- Schema markup must match the visible content on the page. Search engines may ignore or penalize structured data that describes content the user cannot see.
- This tool generates starter markup but does not validate the output against Schema.org schemas. Run the generated JSON-LD through Google Rich Results Test or Schema.org Validator before publishing.
- Some rich result types have strict requirements beyond basic schema fields. Article, FAQ, and Review types may require additional properties for eligibility in search result enhancements.
