JSON-LD Generator
for Rich Results, Not Just Valid Syntax

Pick a schema type — Article, FAQ, Product, LocalBusiness, SoftwareApplication, Breadcrumb, Person, Organization, or Website — fill in real fields, and get a live eligibility checklist scored against Google's actual Rich Results requirements, not just schema.org validity.

  • 10 schema types in one tool
  • Live Rich Results eligibility checklist
  • HTML & Next.js Script output

A generic news/editorial article. Powers the Article rich result in Google Search.

What is JSON-LD structured data?

JSON-LD (JavaScript Object Notation for Linked Data) is the format Google, Bing, and most AI assistants recommend for describing what a page actually is — an article, a product, a FAQ, a local business — rather than just what it says. It lives in a single <script type="application/ld+json"> tag and has zero effect on how the page looks, only on how search engines and assistants interpret it.

Why valid JSON-LD isn't the same as rich-result eligibility

A JSON-LD block can pass every schema.org validator and still never trigger a rich result in Google Search. Google layers its own, narrower set of required and recommended properties on top of schema.org's much looser spec — an Article missing an author, or a Product missing a complete offers block, is perfectly valid JSON-LD that Google will simply ignore for rich-result purposes. That gap is exactly what the eligibility panel on this page checks for, live, as you fill in each field.

What this JSON-LD generator supports

  • Article & BlogPosting — headline, author, publisher, and dates for editorial content.
  • FAQPage — dynamic question/answer pairs for expandable FAQ dropdowns.
  • Organization — company identity, logo, and social profile links for Knowledge Panel eligibility.
  • LocalBusiness — address, geo-coordinates, phone, and opening hours for local search.
  • Product — price, availability, and aggregate rating for Merchant listings.
  • SoftwareApplication — category, platform, price, and rating for apps and SaaS tools.
  • BreadcrumbList — a dynamic navigation trail shown under a search result.
  • Person — author bios and team/profile pages.
  • WebSite — site-wide identity, optionally enabling the Sitelinks Search Box.

How to use it

  1. Pick the schema type that matches your page.
  2. Fill in the fields — required ones are validated before you can generate output.
  3. Check the Rich Results eligibility panel and resolve anything flagged as missing or recommended.
  4. Copy either the raw HTML script tag or the Next.js Script snippet.
  5. Confirm with Google's own Rich Results Test before shipping to production.

Frequently asked questions

How is this different from a generic JSON-LD generator?

Most generators only check that your output is syntactically valid JSON-LD. This tool separately checks it against Google's actual Rich Results requirements per type — a headline with no author, or a Product with no offer, is valid JSON-LD but still won't earn a rich result. The eligibility panel catches that gap.

Which types actually show a visible rich result in Google Search?

Article, Product, BreadcrumbList, and SoftwareApplication can all show enhanced results directly. FAQPage is currently limited to well-known, authoritative sites in Google's own guidelines, but it's still valid and useful for other search engines and AI assistants that read structured data. Organization, Person, and WebSite mainly power Knowledge Panels and the Sitelinks Search Box rather than per-result enhancements.

Do I need to pick between the HTML and Next.js output?

Use the HTML tab for a plain HTML `<script>` tag you can paste into any site. Use the Next.js tab if you're rendering it from a Server or Client Component with `next/script` — it includes a ready `id` and the correct `dangerouslySetInnerHTML` pattern.

Can I add more than one JSON-LD block to the same page?

Yes, and it's common — a blog post page often ships both a BlogPosting block and a BreadcrumbList block. Generate each type separately with this tool and render both `<Script>` tags on the same page with unique `id` values.

Does this tool send my data anywhere?

No. Every field you type, and the JSON-LD it produces, stays entirely in your browser — nothing is sent to a server or stored.

Why do some fields say "optional" but still affect the eligibility panel?

Schema.org validity and Google's Rich Results eligibility are two different bars. A field can be optional for valid JSON-LD (like a Product's aggregateRating) while still being flagged as recommended in the eligibility panel because leaving it out reduces your actual chances of a rich result.
