Schema Markup Generator
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.

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
@idinside 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
@graphcompose mode with@idlinks. - 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.

À propos de l’outil
Générez du JSON-LD Schema pour 19 types ciblés ou parcourez les 921 types Schema.org vendorisés, avec propriétés héritées, plages attendues et badges de prise en charge honnêtes. Les formulaires valident les règles de résultats enrichis de Google et mettent à jour un aperçu SERP.
Fonctionnalités
- Dix-neuf formulaires ciblés et catalogue complet Schema.org avec propriétés héritées.
- Validation Google des résultats enrichis, validation de vocabulaire et aperçu SERP en direct.
- Six sorties : JSON-LD, script HTML, Astro, Next.js, GTM et WordPress.
- Enregistrement automatique, import/export et liens partageables dans le navigateur.
Fonctionnement
Le générateur construit un graphe schema.org, valide les formulaires ciblés selon les exigences actuelles de Google et valide les types du catalogue avec le vocabulaire Schema.org vendorié. Les entités réutilisables sont reliées par @id plutôt que dupliquées.
Limites
- Un balisage valide peut rendre un résultat pris en charge possible, jamais garanti : les moteurs décident de l’éligibilité et de l’affichage.
- Le préremplissage par URL en direct utilise uniquement l’URL demandée via le point de terminaison protégé et ne remplace jamais une valeur déjà saisie.
Questions fréquentes
Quels types Schema cet outil peut-il générer ?
Il propose 19 formulaires ciblés et un navigateur couvrant les 921 types Schema.org vendorisés, avec propriétés héritées et plages attendues.
La génération d’un Schema garantit-elle un résultat enrichi ?
Non. Un balisage valide peut rendre un résultat pris en charge possible, mais les moteurs décident de l’éligibilité et de l’affichage.
JSON-LD, Microdata ou RDFa ?
Le générateur produit du JSON-LD, le format recommandé par Google, ainsi que des extraits pour HTML et plusieurs frameworks.
Où placer le code généré ?
Ajoutez le JSON-LD dans un élément script de la page concernée ou utilisez l’extrait du framework fourni. Les entités Person et Organization peuvent être liées dans un @graph.
Ce que je saisis est-il téléversé ou enregistré ?
La génération, la validation, l’aperçu, l’enregistrement automatique et l’export/import se déroulent dans votre navigateur. Seule une URL demandée explicitement passe par le point de terminaison protégé.
