Generate schema.org JSON-LD from your fields
Pick a type and enter your fields as “key: value” lines. This generator builds valid schema.org markup and checks it for common issues.
Why schema markup matters
Tell machines what your page is
Schema markup is schema.org JSON-LD that labels your page — a business, an article, a product — so search engines and AI assistants can understand and reuse it instead of guessing from raw HTML. It can power rich results and gives assistants clean, structured facts to quote.
The markup is easy to get subtly wrong — a missing required field, a relative URL, or an unescaped character will break it. This generator builds valid markup and flags weak spots in one step.
What weak or missing markup costs you
- Your page never qualifies for rich results
- Assistants describe your page from guesswork
- Invalid JSON-LD is silently ignored by crawlers
- Competitors with clean markup get understood instead
How the Schema Markup Generator works
Pick a type, enter your fields, and the generator builds valid schema.org JSON-LD you can copy straight into your page.
Enter your fields
One “key: value” per line. The generator maps known fields and skips the rest.
Copy and paste
Drop the JSON-LD into a script tag on your page. Each check is marked pass, improve, or fix.
The checks that matter
What this generator validates
These are the things that make schema markup useful to AI assistants and search engines.
Type — a real schema.org type
Required — the must-have fields
URLs — absolute http(s) links
Completeness — enough recommended fields
Valid — well-formed JSON-LD
Safe — escaped for a script tag

What does the schema markup generator do?
It turns a schema type and a few fields into valid schema.org JSON-LD. Pick Organization, Article, Product, LocalBusiness, WebSite, or Breadcrumb, enter your fields, and it builds markup you can paste into your page.
What is schema markup?
Schema markup (structured data) is JSON-LD that labels what your page is about — a business, an article, a product — so search engines and AI assistants can understand and reuse it instead of guessing from raw HTML.
How do I enter my fields?
Enter one field per line as “key: value” — for example “name: AEOMaster” and “url: https://aeomaster.net”. Each type has its own required and recommended fields, listed on the page.
Where do I put the generated JSON-LD?
Copy the generated JSON-LD and paste it inside a <script type="application/ld+json"> tag in your page's <head> or <body>. The markup should match what's visible on the page.
Does it crawl my site or call AI?
It runs entirely on the fields you enter — no login, no crawling, no AI calls. Every check is a structural fact about your input, so the score is deterministic, not a guess.
Does schema markup guarantee AI will cite me?
No. Valid markup helps machines parse your page, but whether AI actually mentions and cites your brand depends on your content, authority, and evidence — which is what the full AEOMaster audit measures.
Beyond this tool
This generator turns your fields into valid schema.org markup. AEOMaster turns that into a full one-time audit of whether AI answers actually mention and cite you — with prioritized fixes.
Prompt-level results across ChatGPT, Claude, Perplexity, Gemini, and Google AI — not just markup.
The sources AI answers cite, and the pages and citations you are missing.
Every finding ranked by expected impact and effort, so you know what to fix first.
Each issue comes with the why, the steps, and an example you can act on.
Re-run it after you ship fixes to confirm your markup and visibility improved.
From valid schema to AI citations
AEOMaster turns your markup into a one-time AI visibility report: prompt-level findings, citation gaps, competitor context, and prioritized fixes you can re-run after each change.
