Pick a type, fill the fields, and copy clean JSON-LD structured data for your page. It's the markup that lets Google show rich results — and lets AI engines like ChatGPT, Claude and Perplexity read your facts as facts instead of guessing from prose. Everything runs in your browser; nothing is sent anywhere.
Paste this inside a <script type="application/ld+json"> tag in the <head> of the matching page. Structured data must describe what's genuinely on the page.
AUDXY checks structured data, content and AI-readability across your whole site — every page, scored, with the fixes that decide whether AI actually quotes you.
Run full AUDXY — free teaser →If you've been told you need "schema markup" but every guide turns into a wall of code, you're in the right place. Schema (the hidden code that tells Google and AI assistants what your page is actually about) shouldn't require a developer just to get started. This free schema markup generator lets you pick what your page is — a business, a service, a list of FAQs, an article — fill in plain fields, and copy clean, valid JSON-LD (the format Google recommends) that you can paste straight onto your site.
You choose a type, type your real details into ordinary form fields, and the tool writes the markup for you in real time. No coding, no guessing at brackets and quotes. Specifically, it builds:
It also strips out any empty fields automatically, so you never ship half-finished markup, and it tells you the moment your code is valid and ready to copy. Everything happens inside your browser — nothing you type is sent anywhere.
Every page you publish is read by three different audiences, and schema speaks to all three:
Below the form you'll see live output and a short status line. A good result says the JSON-LD is valid and ready to copy — that means the fields you filled in produced properly formed code with no missing brackets. A "fill in a field" message isn't an error; it just means the tool is waiting for real details before it writes anything, because empty schema is worse than none. If your output looks short, that's normal — only the fields you actually filled appear, which keeps the markup honest and clutter-free. The real test comes after you publish: paste your page into Google's Rich Results Test to confirm the live page passes.
If you're starting from scratch, work in this order:
Not sure which pages are missing markup? The schema gap finder shows you which of your pages have no structured data yet. To make sure machines understand who and what your brand is, run the entity clarity checker. And if you want AI crawlers to find your content cleanly, the llms.txt generator builds the file that points them to your best pages. Browse the full set on the free tools hub.
Schema markup is structured data — written as JSON-LD — that tells search engines and AI answer engines exactly what your page is about: that this is an Organization, that this block is a list of FAQs, that this is a Service in a specific area. Google uses it to power rich results like star ratings, FAQ accordions and business info panels; AI engines like ChatGPT, Claude and Perplexity lean on the same structure to extract and cite your facts confidently instead of inferring them from prose. Clean, accurate JSON-LD removes the guesswork the machines would otherwise have to do.
Copy the output above and paste it inside a <script type="application/ld+json"> tag in the <head> of the matching page — Organization markup on your homepage, FAQPage markup on a page that actually shows those questions, an Article block on the article itself, and so on. The structured data must describe what is genuinely on the page; don't mark up FAQs or reviews that aren't really there. After deploying, validate with Google's Rich Results Test and the Schema.org validator, then re-generate here whenever the details change.
Yes — it's completely free, with no signup and no limits. Everything runs inside your own browser, so the details you type are never sent to a server. Generate as much JSON-LD as you need and copy it straight into your site.
Match the type to what a visitor actually sees on the page. Use Organization on your homepage or about page, LocalBusiness if you have a physical address customers visit, Service for a single thing you sell, FAQPage on a page that visibly lists questions and answers, and Article on a blog post. If a page does more than one job, you can add more than one block.
On its own, schema markup isn't a direct ranking boost — but it helps Google understand and display your page, which can earn rich results like FAQ drop-downs and business panels that lift how often people click your listing. It also makes your facts easy for AI assistants to quote accurately, which is fast becoming its own source of visitors.
After you paste the code into your page and publish it, run the live page through Google's Rich Results Test and the Schema.org validator. Both read the page directly, confirm the JSON-LD is well-formed, and flag any required fields you've left out before search engines act on it. If you'd rather have your whole site checked at once, the free website audit reviews structured data, content and AI-readability page by page.
Usually not. If you use WordPress, Webflow, Squarespace, Shopify or a similar platform, you can paste the JSON-LD into a custom-code or header block on the matching page. The only rule is that it belongs on the page it describes, and the markup must honestly match what's shown there.
