HOW IT WORKS
From form to rich-result markup in three steps
Structured data tells Google and AI answer engines exactly what a page is about. Valid JSON-LD can earn rich results and makes your content easier for ChatGPT, Gemini and Perplexity to cite.
Pick a schema type
Choose the type that matches your page: Article, Product, FAQ, Local Business, Organization or Breadcrumb.
Fill the fields
Enter your details. The JSON-LD builds live and is checked against the required Schema.org properties as you type.
Copy and paste
Drop the script into your page’s <head>, then confirm it with the Rich Results Test or our Schema Markup Validator.
WHAT THIS TOOL GENERATES
Schema types the generator supports
Each type outputs Google-eligible JSON-LD with the required properties in place and the recommended ones prompted.
Article & BlogPosting
Headline, author, publisher, dates and image - the markup blog posts and news pages need to qualify for article rich results.
Product & Offer
Name, brand, SKU, price, currency, availability and optional aggregate rating for product result eligibility.
FAQPage
Add any number of question and answer pairs; the tool builds a valid mainEntity array of Question and Answer entities.
LocalBusiness
Name, full postal address, phone, price range and URL - the core fields local businesses need for map and local results.
Organization
Name, URL, logo and sameAs social profiles, the entity signals that help search and AI engines understand your brand.
BreadcrumbList
Ordered name and URL items that build a valid breadcrumb trail for the breadcrumb rich result.
GENERATOR VS HAND-CODING
Skip the syntax errors a hand-written tag invites
Writing JSON-LD by hand is where trailing commas, wrong casing and relative URLs creep in. A generator removes the syntax risk, then you confirm the result in the Schema Markup Validator.

| Valid JSON-LD syntax | ✓ Always | Error-prone | ✓ |

Markup only helps when it matches the visible page content. Don’t mark up data a visitor can’t see.
FAQ
Schema markup generator questions
What is a schema markup generator?
A schema markup generator is a tool that turns a simple form into valid JSON-LD structured data. Instead of writing the code by hand, you pick a type and fill in the fields, and the tool outputs a ready-to-paste script for your page’s head.
Is this schema generator free?
Yes. It is completely free, with no signup, and it runs entirely in your browser - nothing you type is uploaded. To audit schema across a whole site, download the free SiteAuditLint desktop app.
What is JSON-LD and why use it?
JSON-LD is Google’s recommended format for structured data. It sits in a single script tag, separate from your visible HTML, which makes it the easiest format to add and maintain.
Where do I put the generated schema?
Paste the full <script type="application/ld+json"> block into the <head> of the matching page. One page can have several blocks for different entities.
Will this guarantee rich results?
No tool can. Valid markup makes a page eligible for rich results, but Google decides when to show them based on content quality, policy and the query. Always confirm with the Rich Results Test.
How do I check the markup is correct?
Run it through our Schema Markup Validator or Google’s Rich Results Test. Both confirm the JSON parses and the required properties are present before you publish.

Schema is added at the template level. One bad template can strip rich results from thousands of pages, and only a crawl finds them all.
