JSON-LD schema generator

The JSON-LD schema generator is a free tool that builds valid structured data — Product, FAQ, Organization or Article — for the answer engines that extract facts before they write prose. Fill in what you know: anything you leave blank is left out, never filled with a plausible-looking placeholder.

Four schema types, valid against schema.org, ready to paste into <head>
Warnings travel with the output, so you know which parts still need checking
No aggregateRating unless you supply real review numbers

Your facts

Paste this into <head>

Fill in the fields and hit Generate.

Why this generator refuses some things. Most schema generators will happily emit an aggregateRating of 4.8 from 127 reviews for a product with no reviews at all. That is a structured-data policy violation, and it is also just false — the two reasons matter equally here. This tool only emits a rating when you supply real numbers, only emits an offer price you confirm matches the page, and only keeps sameAs profiles that are real URLs. Every FAQ answer in your markup must also be visible to a human on the page.

Structured data makes you readable. Whether engines can reach you at all is a different question — check your AI crawler access → — and whether they actually cite you is a third: run a free page audit →
