Frequently Asked Questions

What is JSON-LD?

JSON-LD (Linked Data) is a method of encoding structured data using JSON. It wraps your data with @context (schema.org) and @type (Article, Product, FAQPage, etc.) for search engine rich results.

What schema types are supported?

All schema.org types: Article, Product, FAQPage, HowTo, LocalBusiness, Event, Recipe, VideoObject, BreadcrumbList, and more.

How do I use the output?

Paste the generated JSON-LD into a <script type='application/ld+json'> tag in your HTML <head>. Google and other search engines parse it for rich snippets and knowledge panels.

Does it validate the output?

Syntax only — the generator emits well-formed JSON-LD, but Google-eligibility (required/recommended properties per type) is not checked here. Paste the output into Google's Rich Results Test before shipping.

When using JSON-LD Generator, is my data stored?

No. All generation happens locally in your browser. No structured data is transmitted.
