Schema makes you quotable. Not recommended.
Structured data removes the technical barrier — it doesn't tell you whether AI actually names you. Run the free visibility scan and see who AI recommends for your niche.
[ Run the free AI visibility scan ]Five types, one job: give AI facts it can't misread.
When an answer engine reads your page it has to guess: is this a product? What does it cost? Is this list a how-to? JSON-LD ends the guessing — it states the facts in the vocabulary (schema.org) every major engine parses. That's why our AEO grader weights structured data heavier than any other single check: pages with recognized, answer-relevant types are simply easier to quote correctly.
Quotable facts
Prices, ratings, authorship, publish dates — the details AI answers get wrong most often — are exactly what Product and Article markup pin down. If the fact is in your JSON-LD, the engine doesn't have to infer it from marketing copy.
FAQ = pre-written answers
FAQPage markup hands the engine a ready question-answer pair in its own format. When a user asks that question, your page is the path of least resistance — which is why FAQ schema shows up disproportionately in cited sources.
Questions.
What is JSON-LD and why does it matter for AI?
JSON-LD is structured data embedded in a script tag: it tells machines — search engines and AI answer engines alike — what your page is in unambiguous terms. Answer engines lean on it to decide whether your page is a product, an article or an FAQ, and to quote facts like prices and ratings correctly.
Which schema type should I use?
Organization for your homepage or about page, Product for pricing and product pages, Article for blog posts and guides, FAQPage for any page that answers questions, HowTo for step-by-step tutorials. One page can carry several types — generate each and embed them all.
Where do I put the generated code?
Copy the script tag into the <head> (or anywhere in the HTML) of the page it describes. In Nuxt/Next/Astro you can also inject it via the framework head API. Then re-test the page — for AI readiness with our AEO Score Grader, for rich results with Google’s Rich Results Test.
Is my data uploaded anywhere?
No. The generator runs 100 % in your browser — nothing you type leaves the page. No signup, no account.
Does schema markup guarantee AI cites me?
No — it removes a technical barrier, it does not create demand. Schema makes your page easy to parse and quote; whether an answer engine actually recommends you depends on your visibility in its sources. That is what the free scan measures, on ChatGPT and Google Gemini.
