Schema Markup Generator — Create JSON-LD Structured Data

This free schema markup generator creates JSON-LD structured data that helps search engines understand your page and show rich results. Schema.org markup describes what a page means — a product, FAQ, recipe, event, or review — and Google can turn it into enhanced listings with star ratings, prices, or FAQ accordions. Google recommends the JSON-LD format, which keeps structured data in a separate script block. Generate valid markup, then test it with Google's Rich Results Test before publishing. Everything is generated locally in your browser.

What is schema markup?

    
Schema markup (structured data) is code in JSON-LD format added to your page's HTML that tells search engines exactly what your content means, not just what it says. It is defined by Schema.org, a collaboration between Google, Bing, Yahoo, and Yandex.

    
When Google understands your content through structured data, it can display rich results — enhanced search listings with star ratings, FAQ dropdowns, price information, event dates, and breadcrumb trails. These rich results have significantly higher click-through rates than plain blue links. JSON-LD (JavaScript Object Notation for Linked Data) is Google's preferred format: it lives in a <script type="application/ld+json"> tag and does not require modifying your HTML structure. Add the generated script tag to the <head> or anywhere in the <body> of your page. Use Google's Rich Results Test to validate before publishing.

What structured data unlocks

    
Schema.org markup — usually embedded as JSON-LD — tells search engines exactly what a page means, not just what it says. Mark up a recipe, product, FAQ, event or review and Google can show rich results: star ratings, prices, FAQ accordions and other enhancements that make your listing larger and more clickable than a plain blue link.

    
JSON-LD is the recommended format

    
Google explicitly prefers JSON-LD, a script block in the page head, over inline Microdata or RDFa because it keeps structured data separate from your visible HTML — easier to add, generate and maintain. The data must accurately describe content the user can actually see; marking up information that isn't on the page violates Google's guidelines and can trigger a manual penalty.

    
Validate before you ship

    
Common errors are missing required properties (a Product without a price or name), wrong data types, and FAQ markup whose answers differ from the visible text. Run any generated schema through Google's Rich Results Test to confirm eligibility before publishing — invalid markup is simply ignored, costing you the enhancement.
