Loading the @graph generator…
One @graph, every node with an @id, cross-linked — not a pile of isolated schema scripts. That is the difference this free generator enforces in code.
Simple process
How to build a connected JSON-LD @graph
-
-
Fill site and page facts
Enter the site root URL (every @id derives from it), Organization / Person / both, page URL, and type-specific fields.
-
Copy the connected @graph
Fix required errors, review yellow recommendations, then copy JSON or a ready <script> tag into your page.
Frequently asked questions
What is a JSON-LD @graph?
A JSON-LD @graph is one script block that holds every schema entity on the page — Website, Organization, WebPage, Article, and so on — each with a stable @id. Entities point at each other by @id instead of duplicating nested objects. Connected graphs help search and answer engines resolve who wrote what, on which site, more reliably than scattered isolated scripts.
What is JSON-LD schema markup?
JSON-LD is the format Google recommends for structured data: a script block that describes the page's entities, such as the organisation, the article or the product, in schema.org vocabulary. Search engines and AI systems read it to understand what the page is about. It does not change what visitors see.
What is the difference between JSON Schema and JSON-LD?
They solve different problems. JSON Schema validates the shape of JSON data in software, for example an API payload. JSON-LD adds meaning to web pages with schema.org types so search engines can read them. For SEO structured data you need JSON-LD; this tool generates JSON-LD.
Why not generate separate schema scripts?
Isolated scripts often repeat the same Organization or Person and never link the page to its publisher. This tool always emits one @graph and wires WebSite → publisher, WebPage → isPartOf / mainEntity, and Article → author / publisher automatically — you cannot accidentally export disconnected stubs.
Is my data sent to a server?
No. The generator runs entirely in your browser. Form values never leave your device; there is no account and no upload step for the free builder.
Which page types are supported?
Article / blog, FAQ, local business, product, web application / free tool, and personal About (ProfilePage). Each profile selects the node set and mainEntity wiring for that page type.
How should I use FAQ schema here?
The FAQ profile does not emit a separate FAQPage stub. It upgrades the WebPage @type to FAQPage and places Question nodes in mainEntity — the correct pattern when the FAQ is the page itself. Answers must match visible page text word-for-word.
How does this relate to the AEO Readiness Checker?
The AEO Readiness Checker scores whether your page already has clear, connected structured data. When it flags fragmented or missing schema, this generator is the natural next step: rebuild one connected @graph, paste it into your theme or SEO plugin, then re-check with the AEO Readiness Checker.
