What is schema markup?

        
Schema markup is structured data you add to a web page to spell out what its content means. It uses the shared schema.org vocabulary to label the entities on a page — that this is an Article with an author and a publish date, that this block is an FAQ, that this is a Product with a price and rating. Instead of leaving a machine to guess from your raw HTML, you hand it an explicit, unambiguous description.

        
The format Google and most AI systems prefer is JSON-LD: a small block of JavaScript Object Notation wrapped in a <script type="application/ld+json"> tag. It sits in your page’s HTML but stays separate from the visible content, so you can add or update it without touching your design. This generator builds that block for you and keeps it valid.


        
Why structured data matters for SEO and AI

        
For traditional search, schema markup is what powers rich results: star ratings, FAQ dropdowns, product prices and breadcrumb trails that make your listing stand out on the results page. Those enhancements can lift click-through, and clean markup helps Google index your content more confidently. Structured data also feeds Google’s Knowledge Graph, the entity database behind knowledge panels — so consistent Organization markup helps search engines connect your brand, logo and official profiles into a single recognised entity rather than a set of loose mentions.

        
For AI search, structured data plays a related role. Assistants like ChatGPT, Perplexity and Google’s AI Overviews have to extract facts from pages quickly and reliably. When your key facts — who you are, what a page is about, what a product costs, the answer to a common question — are stated in structured data, there’s far less ambiguity for a model to resolve. Schema doesn’t force an AI to cite you, and it’s one signal among content quality and site health rather than a magic switch. But it removes friction: it makes your pages easier to read correctly, which is exactly what you want when a model is deciding what to quote.


        
Schema types this generator supports

        
Start with the types that do the most work for the most sites:

        
    
          
  • Organization — your company’s identity, logo and official profiles, a foundation for entity recognition.
    • 
          
  • Article — blog posts and editorial content, with author, publisher and dates.
    • 
          
  • FAQPage — question-and-answer content that can earn expandable FAQ rich results.
    • 
          
  • Product — items for sale, with price, availability and optional aggregate rating.
    • 
          
  • LocalBusiness — physical locations, with address, phone and opening hours.
    • 
          
  • BreadcrumbList — your page’s position in the site hierarchy.
    • 
        


        
Why JSON-LD is the format to use

        
There are three ways to add structured data to a page: JSON-LD, microdata and RDFa. Microdata and RDFa weave attributes directly into your visible HTML, which makes them fiddly to maintain and easy to break when you change your markup. JSON-LD keeps the structured data in a single self-contained block, separate from the content it describes. Google explicitly recommends JSON-LD, it’s the easiest format to generate and update programmatically, and it’s what most AI systems expect — which is why this generator outputs JSON-LD and nothing else. You can drop the block into any page without rewriting your templates.


        
How to use it, and where to paste the code

        
Choose a schema type, fill in the fields that apply, and watch the JSON-LD build on the right — blank fields are left out automatically so you never ship empty properties. When it’s ready, hit Copy and paste the whole <script> block into your page’s HTML, ideally inside the <head> or just before the closing </body> tag. Most content platforms let you add a custom HTML or header snippet; on WordPress you can drop it into a Custom HTML block or your theme’s header. Everything runs locally in your browser, so nothing you type is uploaded anywhere.

        
Add markup that matches what’s actually visible on the page — Google’s guidelines require the structured data to reflect real, on-page content. Marking up content a visitor can’t see, or inflating ratings and prices, is the fastest way to get flagged for spammy structured data and lose your rich results. Before publishing, paste your output into Google’s Rich Results Test or the schema.org validator to confirm it’s error-free, and re-check it whenever the underlying page changes so your markup never drifts from reality.


        
Structured data is one piece of AI visibility

        
Valid schema makes individual pages legible, but getting cited by AI is a whole-site effort: clear content, sound technical health, and a real read on how assistants describe you today. That’s what Suparank is built for — it measures your visibility across ChatGPT, Perplexity, Gemini and Claude, runs GEO and technical audits that flag missing or broken markup, and helps you write content AI actually quotes, all from one chat-first workspace.

      

    

  

  

  	

		

			

				
Frequently asked questions

			

			

									

						What is a schema markup generator?
						
A schema markup generator is a tool that builds structured data for your web pages without hand-writing code. You pick a type and fill in a short form, and it outputs valid JSON-LD you can paste into your page so search engines and AI systems understand your content.

					

										

						What is schema markup?
						
Schema markup is structured data that labels what your content means using the shared schema.org vocabulary, for example marking a page as an Article, an FAQ or a Product. It helps machines read your page accurately instead of guessing from raw HTML.

					

										

						Is schema markup still relevant?
						
Yes. Schema markup powers rich results in Google, such as star ratings and FAQ dropdowns, and it helps AI systems extract facts from your pages reliably. As AI search grows, giving models unambiguous, structured facts is more useful, not less.

					

										

						Does schema markup help with AI search?
						
It makes your key facts explicit, so assistants like ChatGPT, Perplexity and Google AI Overviews have less to resolve when deciding what to quote. Schema does not force an AI to cite you, but it removes friction by making your pages easier to read correctly.

					

										

						Where do I add the JSON-LD to my page?
						
Paste the full script block into your page HTML, ideally in the head or just before the closing body tag. Most platforms allow a custom HTML or header snippet; on WordPress you can use a Custom HTML block or your theme header.

					

										

						Is this schema generator free?
						
Yes. The Suparank schema markup generator is free, needs no sign-up, and runs in your browser. The JSON-LD it produces is yours to copy and paste into any site.
