Schema Markup Generator

Free tool

Start with the 19 curated high-value forms — Article, Product, Recipe, Event, LocalBusiness, VideoObject, JobPosting, Dataset, SoftwareApplication, QAPage, and more — or browse all 921 types in the vendored Schema.org vocabulary. The universal editor derives inherited applicable properties and expected ranges; it never treats Schema.org validity as a promise of a search-engine feature.

Everything runs in your browser: live SERP preview for curated types, reusable Person/Organization entities linked by @id inside an @graph, paste-and-audit for existing markup, autosave, export/import, shareable links, generic JSON-LD output for catalog types, and a separate stable OpenAI/ChatGPT flat product-feed panel with CSV and JSONL exports.

Runs in your browser — uploads are not sent to our server, but the current project is autosaved in this browser’s local storage until you replace it or clear this site’s browser data. If you choose live-URL prefill, only that public URL is sent to this site's guarded fetch endpoint. Anonymous run-level outcome counters may be used for aggregate research; URLs, domains, IPs, and identifiers are never included, and no statistic is released below 100 runs.

Local data

Saved targets, named lists, and recent check summaries remain only in this browser.

How to use it

Pick one of 19 curated schema types, browse all Schema.org types, or compose Article, Organization, WebSite, and BreadcrumbList into one @graph.
Fill in the fields. The tool validates as you type against Google's current rich-result requirements and updates the live SERP preview.
Reuse a Person or Organization you've already built — they're linked by @id inside a single @graph, so you don't repeat yourself.
Copy the output in the format you need: raw JSON-LD, an HTML <script> tag, or a ready-to-paste Astro, Next.js, Google Tag Manager, or WordPress snippet.

Sample report

An Article with a linked author comes out as:

{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "How redirect chains affect SEO",
  "author": { "@type": "Person", "name": "Patrick Stox" },
  "datePublished": "2026-07-08",
  "image": "https://example.com/cover.jpg"
}

Paste that into your page's <head> as a <script type="application/ld+json"> block. The generator validates it live — a missing required property (say headline or image) is flagged before you ship, and reusable entities are wired together with @id instead of duplicated.

What the validation tells you

As you type, each field is checked against Google's documented rich-result rules for that type — required properties that block eligibility, recommended ones that improve it, and retired features it warns you off. Meeting every requirement makes a rich result possible, never guaranteed: Google decides at query time, and some result types no longer exist (FAQ rich results were retired in May 2026 — the tool says so rather than letting you chase a gone listing).

How it works

Everything runs in your browser. The generator builds a schema.org @graph; curated forms validate against Google's current requirements, while catalog types validate against the vendored Schema.org vocabulary and show only documented engine badges. It renders curated SERP previews and emits six output formats. Autosave, export/import, and shareable links are all client-side. When you choose live-URL prefill, the URL is fetched through the site's guarded text-fetch endpoint; the tool only fills fields you have left empty.

Features

Nineteen focused forms plus all 921 vendored Schema.org types, with inherited properties and expected ranges for generic types.
Google rich-result validation and a live SERP preview for curated forms; vocabulary/range validation for catalog types.
Reusable Person/Organization entities and a full @graph compose mode with @id links.
Six outputs: JSON-LD, HTML script tag, Astro, Next.js, GTM, WordPress.
Autosave, export/import, and shareable links — all in-browser.

Limitations

It generates JSON-LD (the format Google recommends), not Microdata or RDFa. The universal browser covers the vendored Schema.org vocabulary, but valid markup is still necessary rather than sufficient for a rich result. Live-URL prefill is intentionally non-destructive: it never replaces a value you have already entered.

Frequently asked questions

Which schema types can this generate?

The generator has 19 curated forms plus a browser for all 921 types in the vendored Schema.org vocabulary. Curated forms use Google-specific checks; catalog types use general vocabulary validation and honest support badges.

Should I use JSON-LD, Microdata, or RDFa?

Google recommends JSON-LD, and it is easier to maintain separately from HTML. This generator outputs JSON-LD plus snippets for HTML, Astro, Next.js, Google Tag Manager, and WordPress.

Does generating schema guarantee a rich result?

No. Valid markup can make a supported result possible, not guaranteed. Search engines decide eligibility and display, and the tool flags retired features rather than promising them.

Where do I put the generated code?

Add the JSON-LD in a script element on the relevant page, or use a provided framework snippet. Reusable Person and Organization entities can be linked by @id inside an @graph.

Is anything I type uploaded or stored?

Normal generation, validation, preview, autosave, and export/import run in your browser. Live-URL prefill fetches only the URL you request through the guarded endpoint.
