Schema markup JSON-LD generator free: build structured data for rich results

Structured data is one of the most underutilized SEO techniques. By adding schema.org JSON-LD markup to your pages, you give Google explicit signals about your content: enabling rich result features like review stars, FAQ accordions, product prices, HowTo step lists, and event details directly in search results. These enhanced snippets occupy more visual space and consistently deliver higher click-through rates.

This free JSON-LD generator supports eight of the most impactful schema types. Fill in the form fields for your chosen type and the complete, correctly formatted JSON-LD script tag is built in real time. Nested fields like publisher logo (Article), aggregate ratings (Product), FAQ pairs, HowTo steps, and geo coordinates (LocalBusiness) are all handled automatically. Copy the output and paste it into your HTML head or CMS, then validate with Google's Rich Results Test.
