How it works

How the schema markup generator works

Turn a few form fields into valid, copy-paste JSON-LD structured data that Google and AI engines can read — in four steps, no code.

Pick a schema type

Choose FAQ, Article, LocalBusiness, Product, Organization or Breadcrumb from the tabs.

Fill in the fields

Enter your details. The JSON-LD builds live on the right as you type — add or remove FAQ rows freely.

Copy the code

One click copies a clean, valid <script type="application/ld+json"> block ready to paste.

Add & validate

Paste it into your page's HTML (or Rank Math's custom schema) and confirm with Google's Rich Results Test.

Structured data generator

What is schema markup (and why it matters)?

Schema markup — also called structured data — is a standardized code format (usually JSON-LD) that tells search engines exactly what your content means, not just what it says. A schema markup generator writes that code for you so you don't have to hand-author it.

With schema in place, Google can show rich results — star ratings, FAQs, prices, breadcrumbs — and AI engines like Google AI Overviews, ChatGPT and Perplexity can parse and cite your content far more reliably. Structured data is one of the fastest, highest-leverage ways to improve both search and AI visibility.

JSON-LD generator

Why JSON-LD is the format to use

There are three ways to add structured data — JSON-LD, Microdata and RDFa — but Google explicitly recommends JSON-LD, and that's what this JSON-LD generator produces. Unlike the older formats, JSON-LD sits in a single tidy script block instead of being tangled through your HTML.

Google's preferred and best-supported format according to official Google Search Central documentation
Lives in one <script> block — easy to add and maintain
Doesn't touch your visible HTML, so it can't break your layout
Works with WordPress, Rank Math custom schema, and any CMS

Paste the generated block into your page's HTML head or body — or into Rank Math's custom schema field — and you're done.

FAQ

Schema markup generator — FAQs

Everything you need to know about structured data, JSON-LD, and rich results.

What is a schema markup generator?

A schema markup generator is a free tool that creates valid structured data (in JSON-LD format) from a simple form. Instead of hand-coding schema, you fill in your details — like FAQ questions or business info — and the tool outputs a ready-to-paste code block that helps search engines and AI engines understand your content.

Is JSON-LD better than Microdata?

Yes — Google explicitly recommends JSON-LD over Microdata and RDFa. JSON-LD lives in a single script block, keeps your structured data separate from your visible HTML, and is far easier to add and maintain. This generator outputs JSON-LD for that reason.

Does schema markup improve SEO?

Schema markup doesn't directly boost rankings, but it makes your pages eligible for rich results and much easier for AI engines to parse and cite. That improved visibility and click-through rate is why structured data is considered one of the highest-leverage technical SEO tasks.

How do I add schema markup to WordPress?

Copy the generated JSON-LD block and paste it into your page — either directly in the HTML, via a custom-HTML block, or into your SEO plugin's custom schema field (for example Rank Math). Then validate it with Google's Rich Results Test to confirm it's error-free.

Which schema type helps most with AI Overviews?

FAQ schema is the most commonly cited structured-data format in AI-generated answers, followed by Article and Product schema. Adding clear FAQ markup to your key pages is one of the fastest ways to improve your chances of appearing in Google AI Overviews and AI search results.

Is this schema generator free?

Yes — completely free, with no signup and no limits. It runs entirely in your browser, so nothing you enter is stored or sent anywhere.
