Free Schema Markup Generator

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.

Answer Engine Optimization (AEO) means getting cited by ChatGPT, Claude, Copilot, 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.

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.

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.

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).

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.

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.

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.
