What is a JSON-LD generator?

A JSON-LD generator builds schema.org structured-data blocks you paste into your HTML . It saves you from hand-writing JSON for Article, Product, FAQ, HowTo, and other rich-result schema types. Output is valid against Google's Rich Results Test.

Where do I paste the generated JSON-LD?

Inside the of your HTML page, wrapped in a tag (the generator includes this wrapper automatically). It can also go in — Google reads either location. In Next.js, use dangerouslySetInnerHTML.

Is this JSON-LD generator free?

Yes — entirely free, no signup, runs in your browser. We generate code on the client; nothing is sent to a server. You can use it commercially without restrictions.

What is JSON-LD?

JSON-LD (JavaScript Object Notation for Linked Data) is Google's preferred format for structured data. You embed a JSON block in a <script type="application/ld+json"> tag, describing your page using schema.org vocabulary. Search engines parse it to display rich results — FAQ accordions, star ratings, breadcrumbs, How-To steps — that have 30-50% higher click-through rates than plain blue links.
