What is JSON-LD structured data?
Structured data is a machine-readable summary of a page, written in a standard vocabulary called Schema.org. JSON-LD is the recommended format: a small block of JSON inside a <script type="application/ld+json"> tag in your page’s <head>.
It does not change how your page looks. Instead, it tells search engines and AI assistants explicit facts — this is an Organization named X, this is a Product that costs Y, these are the questions on this FAQ page — so they do not have to guess from the raw text.
Why it matters for AI and search
Search engines use structured data to build rich results, and AI assistants increasingly read it to answer questions accurately. When your facts are stated explicitly, a machine is far less likely to misread a price, mix up an author, or miss that a page is a set of FAQs.
Structured data is one of the ten things our AI-friendliness checker scores, and it is one of the easiest wins: it is invisible to visitors, quick to add, and it directly helps both classic search and the new AI answer engines understand your page.

Frequently asked questions
- Is this JSON-LD generator free?
- Yes. Generate and validate as much structured data as you like, with no signup and no credit card.
- Where do I put the generated code?
- Paste the whole <script type="application/ld+json"> block inside the <head> of your page. You can add more than one block for different types.
- Will structured data change how my page looks?
- No. JSON-LD is invisible to visitors. It only adds machine-readable facts for search engines and AI assistants.
- Does the tool invent data to fill gaps?
- No. Only the fields you fill in are included. Empty optional fields are left out, so the output always reflects your real data.
