In-depth guide
Structured data is a standardised vocabulary (schema.org) that describes what a page is about — an article, a product, an FAQ, a recipe — in a way machines can parse. Google reads it to unlock rich results like star ratings, FAQ accordions and breadcrumbs. This tool generates clean JSON-LD blocks you can drop into a page.
Google recommends JSON-LD over Microdata or RDFa because it lives in a single <script type="application/ld+json"> block instead of being woven through your HTML. That keeps your markup clean and makes the structured data easy to generate, audit and update without touching the visible page.
Article, Product, FAQPage, WebPage).<head> or body of the matching page, then extend it with any optional fields the type supports.The golden rule: structured data must describe content that is actually visible on the page. Marking up a review that users cannot see, or a price that differs from the page, is a policy violation that can earn a manual action. Always test the output in Google's Rich Results Test and the Schema Markup Validator before shipping.
Use this tool for quick browser-based work when you need an answer or output immediately. Use a dedicated application or automated workflow when you need bulk processing, approvals, or repeatable production rules.
Any schema.org type string, such as WebPage, Article, Product, FAQPage or BreadcrumbList. Pick the type that best matches the page's primary content.
Yes. The output is a structured JSON-LD block ready to drop inside a script type=application/ld+json tag.
Yes. Use the output as a starter and extend the JSON with the full property set your chosen type supports.
Google recommends JSON-LD because it lives in one script block rather than being woven through your HTML, keeping markup clean and easy to maintain.
No. Valid markup makes a page eligible for rich results, but Google still decides whether to show the enhanced treatment.
No. Structured data must describe content users can actually see. Marking up hidden reviews or mismatched prices is a policy violation that can trigger a manual action.
