free schema markup generator (JSON-LD) by Devlet Tech — structured data powering SEO and GEO
Structured data is the bridge from classic SEO to GEO — how AI engines read and cite your pages

Key takeaways

  • A schema markup generator turns a simple form into valid JSON-LD structured data — no hand-coding.
  • Google recommends JSON-LD over Microdata; it lives in one clean script block.
  • FAQ schema is the most-cited structured-data format in AI Overviews and ChatGPT answers.
  • Schema doesn't boost rankings directly — it unlocks rich results and makes pages easier for AI to cite.
  • Always confirm your markup with Google's Rich Results Test before publishing.
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.

01

Pick a schema type

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

02

Fill in the fields

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

03

Copy the code

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

04

Add & validate

Paste it into your page or Rank Math's custom schema, then confirm with Google's Rich Results Test.

Structured data generator

What is schema markup?

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

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. It's one of the fastest, highest-leverage ways to improve both search and AI visibility.

  • Win rich results that take up more space and earn more clicks
  • Make your pages easier for AI engines to understand and cite
  • Declare authorship, ratings and business details per Schema.org vocabulary
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, best-supported format per Google Search Central
  • 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

AEO & GEO

How schema markup gets you cited by AI

Structured data is now a core part of Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO) — the practice of getting your pages quoted inside AI answers.

When ChatGPT, Perplexity or a Google AI Overview builds an answer, it needs to quickly understand which part of your page answers the question. Schema markup hands the machine that answer on a plate. FAQ and HowTo schema in particular map cleanly to the question-and-answer shape of AI responses, which is why marked-up pages are cited disproportionately often.

Direct answer: Schema markup doesn't rank you higher on its own, but it makes your content machine-readable — so answer engines can extract, trust and cite it. Pair clear FAQ/Article schema with genuinely helpful content and you dramatically raise your odds of being the source an AI quotes.

We go deep on this in our guides to getting cited by ChatGPT and the difference between AEO and SEO — both start with a machine-readable page, and schema is step one.

Structured data is the bridge to GEO

Classic SEO optimizes for a ranked list of blue links. GEO optimizes to be the answer itself. Entities, relationships and explicit facts — exactly what schema encodes — are what large language models lean on when they decide what's true and who to credit.

Once you've generated and published your schema here, the natural next step is to check whether AI engines actually surface your pages. Our sister tool, the AI Overview Checker by H&U Solutions, scores how ready a URL is to appear in Google AI Overviews — a useful companion to this generator.

How to add schema markup in WordPress

Generated your JSON-LD above? Here's how to get it live and validated in four steps.

01

Generate & copy

Pick your type above, fill the fields, and copy the JSON-LD block.

02

Paste into the page

Use a Custom HTML block, your theme's header/footer scripts, or Rank Math's custom-schema field.

03

Avoid duplicates

Don't ship the same schema twice — if Rank Math already outputs Article/FAQ for that page, use only one source.

04

Validate

Run the URL through the Rich Results Test and Schema Validator.

Avoid these

Common schema markup mistakes

The errors that get rich results ignored — or trigger warnings in Search Console.

Marking up invisible content

Schema must reflect content actually visible on the page. FAQ schema for questions a user can't see is a guideline violation.

Shipping duplicate schema

Outputting the same FAQ or Article schema from both your plugin and a manual block confuses parsers. Keep one source of truth.

Required fields missing

Product without an offer, or Article without a headline, won't earn rich results. Fill every required property.

Never validating

A single stray comma breaks the whole block. Always run the Rich Results Test before and after publishing.

Plain-English glossary

Structured data terms, explained simply

The vocabulary around schema, without the jargon.

JSON-LD
A script-based format for structured data that Google recommends. It sits in one block and doesn't touch your visible HTML.
Rich result
An enhanced search listing — stars, FAQs, prices, images — made possible by schema markup on the page.
Entity
A distinct thing (a person, brand, product) that search and AI engines recognize and connect. Schema declares entities explicitly.
Knowledge panel
The info box on the right of some searches. Organization and LocalBusiness schema feed the data behind it.
AEO
Answer Engine Optimization — optimizing to be quoted by answer engines like Google AI Overviews and ChatGPT.
GEO
Generative Engine Optimization — the broader practice of being surfaced and cited inside AI-generated content.
FAQ

Schema markup generator — FAQs

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

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.
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.
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.
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.
FAQ schema is the most commonly cited structured-data format in AI-generated answers, followed by Article and HowTo 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.
Always. A single misplaced comma can break an entire JSON-LD block. Run every page through Google's Rich Results Test and the Schema.org validator after adding markup — the tool outputs valid JSON-LD, but you should confirm it once it's live on your page.
Yes — completely free, with no signup and no limits. It runs entirely in your browser, so nothing you enter is stored or sent anywhere.
Advanced

Questions from developers & SEOs

Yes. A single page can carry several types — for example Article + FAQPage + BreadcrumbList. Add each as its own JSON-LD block or combine them in a graph. Just make sure each type accurately reflects the content that's actually on the page.
Google accepts JSON-LD in either the head or the body, and it can even be injected by JavaScript. In WordPress the simplest reliable spots are your SEO plugin's schema field or a header script. Consistency matters more than location.
WebSite schema with a SearchAction makes your site eligible for a Sitelinks search box in Google results, but Google decides whether to show it. It's worth adding on your homepage — generate it from the WebSite tab above.
Not a direct ranking factor. Its value is indirect but real: it earns rich results, lifts click-through rate, and makes your content easier for AI engines to extract and cite. Combined with helpful content, that adds up to meaningful visibility gains.
