Schema Markup Generator
Produce structured data that validates, without hand-writing JSON or remembering which properties each type requires.
How Schema Generator works
Generate valid JSON-LD for Article, Product, FAQ, LocalBusiness, Organization, Breadcrumb and Video, ready to paste in head. Everything happens inside this page: the tool reads your input, runs the calculation or conversion locally, and hands the result back to you. Nothing is transmitted, because there is no backend to transmit it to.
That design choice is deliberate. Most free tool sites upload your files to a server, process them there, and quietly keep a copy. Toolcin cannot do that — the site is a set of static files. If your connection dropped the moment the page finished loading, every tool would still work.
What structured data does
Schema markup describes a page in a vocabulary search engines understand: this is an Article with this author and date, this is a Product with this price, these are the questions and answers on the page.
It does not change ranking directly. It makes a page eligible for richer presentation — breadcrumbs, review stars, FAQ accordions — and it removes ambiguity about what the page is.
The types worth using
Article, Product, FAQPage, LocalBusiness, Organization, BreadcrumbList and VideoObject cover the overwhelming majority of pages. Each needs specific required fields, and a missing required field disqualifies the markup silently.
Breadcrumb and Organization are the two that almost every site should have; FAQPage only pays off when the questions are genuinely visible on the page.
| Type | Needs at minimum |
|---|---|
| Article | headline, image, datePublished, author |
| Product | name, image, offers (price, currency) |
| FAQPage | questions with accepted answers |
| LocalBusiness | name, address, telephone |
| BreadcrumbList | ordered items with names and URLs |
Markup must match the page
Structured data that describes content not visible on the page is a policy violation, not a clever trick. Prices, ratings and FAQs must be readable by a visitor, or the markup can be ignored or penalised.
Validate the output in a rich-results test before publishing — a single missing comma makes the whole block invalid JSON and the crawler sees nothing.

Questions
Where does JSON-LD go?
Inside a script tag with type application/ld+json, in head or body. Head is the convention.
Will this guarantee rich results?
No. It makes a page eligible; Google decides whether to show a rich result based on quality and policy.
Can I have several schema blocks?
Yes. One JSON-LD block with an @graph array is the cleanest way to keep them together.
Do I need JSON-LD or microdata?
JSON-LD is what Google recommends and it is easier to maintain.
