Built for Answer Engine Optimization

Most generators target Google rich snippets. Ours targets every crawler that reads structured data — including the AI assistants users actually ask now.

12 schema types covered

Organization, LocalBusiness, Article, Product, FAQPage, HowTo, VideoObject, Person, Event, Recipe, BreadcrumbList, SoftwareApplication — the full set of rich-result-eligible types.

Live JSON-LD preview

Output updates as you type. Toggle between raw JSON-LD and a ready-to-paste <script> tag. Copy with one click.

AEO-ready, not just SEO

Built around what AI crawlers actually read — sameAs entity signals, complete addresses, ISO-formatted dates and durations. Validates clean in Google Rich Results.

How to install schema on your page

Three ways to drop the generated JSON-LD onto a live page. Pick the one that matches your stack.

Plain HTML / static site

Paste the <script type='application/ld+json'>…</script> block inside your <head>. That's it — no JavaScript, no build step. Most CMSes and static-site generators (Hugo, Astro, 11ty, Jekyll) accept raw <head> snippets via a layout or shortcode.

Next.js / React

Render a plain <script type='application/ld+json'> tag in your layout or page component, with the JSON serialized via dangerouslySetInnerHTML. Do NOT use next/script with the beforeInteractive strategy — it serializes the JSON into a deferred TURBOPACK array that AI crawlers can't see in the raw HTML.

WordPress

Easiest: install RankMath or Yoast — both let you map page fields to schema and emit it automatically. If you're hand-rolling: paste the snippet into your theme's header.php inside the <head>, or use a snippets plugin to inject it per-page.

Frequently asked questions

Everything you need to know about schema markup, JSON-LD, and how it fits into AEO.

What is schema markup?
Schema markup is structured data — a vocabulary defined by schema.org — that you embed in a page to tell search engines and AI assistants exactly what the page is about. Instead of guessing whether a number on the page is a price or a phone number, crawlers read your schema and know for certain. The most common format is JSON-LD, a small JSON object placed inside a <script type='application/ld+json'> tag in the page head.
Why does schema markup matter for AEO?
Answer Engine Optimization (AEO) means getting cited by ChatGPT, Claude, Gemini, Perplexity, and other AI assistants. Those models lean heavily on structured data to disambiguate entities, attach facts to brands, and pick which sources to cite. Pages with valid schema are recommended more often — schema is the most direct, machine-readable way to tell an AI exactly what your page is about.
Is JSON-LD better than Microdata or RDFa?
Yes. Google, Bing, and every major AI crawler treat JSON-LD as the preferred format because it's decoupled from your visible HTML — no risk of breaking on a template change. The whole block lives in the <head>, is easy to lint, and can be generated from your CMS without touching markup. Microdata and RDFa still work but require inline attribute soup that's brittle and harder to maintain.
Where do I paste the generated schema?
Drop the <script type='application/ld+json'>...</script> block inside your page's <head> (preferred) or at the end of <body>. For Next.js, render it as a regular <script> in your layout or page component — do NOT use next/script with beforeInteractive, which serializes the JSON into a deferred array that crawlers can't see. For WordPress, paste it into the theme's header.php or use a plugin like RankMath / Yoast.
Can I use multiple schema types on one page?
Yes — and you should. A typical blog post might emit Article + BreadcrumbList + Organization (publisher) + Person (author). Each goes in its own <script type='application/ld+json'> block. Google reads them as a graph and uses whichever fits the surface (Rich Results, AI Overview, knowledge panel).
How do I validate the schema I just generated?
Two tools, both free: Google's Rich Results Test (search.google.com/test/rich-results) tells you which Google rich result types your schema is eligible for. Schema.org's validator (validator.schema.org) checks raw spec compliance — useful when Google's tool says 'parsed but not eligible' and you want to know why. Both accept pasted code, no URL required.
Will adding schema make my site rank #1?
No. Schema is necessary, not sufficient. It makes your pages eligible for rich results, helps AI assistants disambiguate your brand, and improves click-through from results pages — but it doesn't change your core ranking signals (content quality, links, technical SEO). Think of it as plumbing: invisible when present, painful when missing.
Is this generator really free?
Yes. Everything runs in your browser — no signup, no rate limit, no upsell. The generated JSON-LD is yours to use anywhere. FixAEO also offers a free site-wide AEO audit if you want to see how your existing schema, citations, and content stack up across the major AI engines.
