FREE TOOL Schema.org JSON-LD generator
Generate valid JSON-LD structured data — the markup that earns rich results and helps AI answer
engines understand and cite your page. Pick a type, fill the fields, copy the block into your
<head>. Runs entirely in your browser.
Why structured data still matters in 2026
Structured data is how you tell a machine what your page is, instead of making it guess
from prose. For classic search, JSON-LD drives rich results — the stars, FAQs, breadcrumbs, and
product cards that make a listing stand out. For answer engines, it does something subtler and
more valuable: it removes ambiguity. A model deciding whether to cite your page reads your schema
to confirm the author, the date, the entity, the question your page answers — exactly the signals
that separate a quotable source from a maybe.
Of the types here, FAQPage is the highest-leverage single addition for AEO: it
maps your content directly onto the question-and-answer shape engines extract. Article
with a real author and date carries the strongest E-E-A-T signals. Organization
establishes your brand as an entity. Add the ones that fit your page — you can include several
blocks on the same page.
How to use the output
- Paste the generated
<script type="application/ld+json"> block into your page's <head>. - Validate with Google's Rich Results Test and the Schema.org validator before shipping.
- Keep it honest — schema that contradicts the visible page can hurt you, not help.
- Want to know if it is actually earning citations? Score the page with our citation-readiness checker or the AEO audit endpoints, which grade schema coverage.
Sources & further reading
The standards this generator follows:
- JSON-LD 1.1 (W3C Recommendation) — the serialization format this tool emits.
- Schema.org (Wikipedia) — the shared vocabulary the types come from.
- RFC 8259 — JSON (IETF, 2017) — the underlying data format.
Common questions
What is JSON-LD schema markup?
JSON-LD is the structured-data format Google and answer engines recommend: a small <script type="application/ld+json"> block in your page's <head> that describes what the page is — an Article, an Organization, a Product, a set of FAQs — in schema.org vocabulary. It makes your content machine-readable, which drives rich results in search and helps AI engines understand and cite your page.
Is this schema generator free?
Yes. It runs entirely in your browser — no signup, nothing uploaded. Pick a type, fill the fields, copy the generated JSON-LD into your page's head.
Which schema types does it support?
The highest-impact types for AEO and rich results: Organization, Article, FAQPage, Product, and BreadcrumbList. FAQPage in particular is one of the strongest single schemas for earning AI-overview and answer-engine citations on question queries.
Where do I put the generated JSON-LD?
Paste the whole <script type="application/ld+json"> block into your page's <head>, or anywhere in the body — search engines accept it in both. One block per type; you can include several blocks on the same page (for example, Article plus BreadcrumbList plus FAQPage).
How do I check my schema is valid?
Validate it with Google's Rich Results Test and the Schema.org validator. To see whether your structured data actually helps you get cited by AI engines, run the page through our citation-readiness checker and AEO audit endpoints, which score schema coverage among other signals.
Markup is half the job.
