The short answer
What schema markup is, and why AI search reads it.
What is schema markup and why does it matter for AI search?
Schema markup is structured data, usually written as JSON-LD in a script tag, that labels what a page is about: that this block is an FAQ, that this is a product with a price, that this is an organization with these profiles. Search engines and AI assistants read it to understand a page without guessing from the raw HTML, which makes the page easier to quote correctly. It does not guarantee a citation, but it removes ambiguity, and clean, accurate structured data on your key pages is one of the cheapest on-page wins in answer engine optimization.

What it builds
Six schema types, the ones engines actually use.
Each type below outputs valid schema.org JSON-LD. Fill only the fields you have; the generator leaves the rest out rather than emitting empty values.
Your company entity: name, URL, logo and the profiles (sameAs) that help models resolve who you are. The backbone of your entity graph.
Question and answer pairs from a page that has them. The format assistants lift most directly into answers.
A blog post or guide: headline, author, dates and image, so engines know it is dated, authored content.
A product with price, currency and availability, and an optional rating, for pages that sell something.
A step-by-step guide as ordered steps, the structure engines quote for how-to questions.
The path to the page, so engines understand where it sits in your site and can show the trail.
How to use it
From fields to valid JSON-LD in two minutes.
No account and no validator to run afterward. The output is valid schema.org by construction.
- Pick a type
- Choose the schema type that matches your page: Organization, FAQPage, Article, Product, HowTo or Breadcrumb.
- Fill in the fields
- Add what you have. Empty fields are dropped, so you never emit a blank property that a validator flags.
- Copy the script
- Copy the ready-to-paste script tag, or download it. It is complete JSON-LD wrapped in a script element.
- Paste it in your head
- Drop the script into the head of the page it describes. One page can carry more than one type.
Structured data must match what a visitor actually sees on the page. Do not mark up content that is not there.
What good looks like
Accurate, matching, and on the right page.
Valid JSON-LD is the easy part. These are the things that separate schema that helps from schema that gets ignored or penalized.
Only mark up content a visitor can actually see. Schema that describes content not on the page is the fastest way to get it ignored.
An FAQ page gets FAQPage, a product page gets Product. The wrong type is worse than none, because it mislabels the page.
Prices, dates, ratings and names must be true and current. Stale or invented values undermine every other signal on the page.
Fill the fields you genuinely have. A richer, accurate entity is more useful to a model than a bare name and URL.
Put the markup in the head of the page it is about, not sitewide. Sitewide FAQ or Product markup describes the wrong pages.
Questions
schema markup questions.
What is schema markup?
Schema markup is structured data added to a page, usually as JSON-LD in a script tag, that labels what the content is: an FAQ, a product, an organization, an article. It uses the shared vocabulary at schema.org so that search engines and AI assistants can read the page's meaning directly instead of inferring it from the HTML.
How do I add schema markup to my site?
Generate the JSON-LD for your page type above, copy the script tag, and paste it into the head of the page it describes. On WordPress, Webflow, Framer or a static site you can add it via a custom-code or head-injection field. One page can carry multiple types, for example an Article plus a BreadcrumbList.
Does schema markup help with AI search and AEO?
It helps by removing ambiguity. AI assistants read structured data to understand a page without guessing, which makes accurate content easier to quote. It is not a ranking or citation guarantee, but clean, accurate schema on your key pages is a cheap, low-risk on-page win in answer engine optimization.
What is JSON-LD and why is it preferred?
JSON-LD is a way to write schema.org structured data as a block of JSON inside a script tag, kept separate from your visible HTML. Google recommends it because it is easy to add and maintain without touching your page markup, and it is the format this generator produces.
Which schema type should I use?
Match the type to the page: Organization for your homepage or about page, FAQPage for a page with questions and answers, Article for a blog post or guide, Product for a product page, HowTo for a step-by-step guide, and BreadcrumbList for the navigation path. When in doubt, mark up the single thing the page is most about.
Is the schema generator free?
Yes. The generator is free, needs no signup, and runs entirely in your browser, so nothing you enter is uploaded. Prefer's paid plans are for the next step: measuring whether ChatGPT, Claude, Gemini and Perplexity actually cite you, and doing the work to change the answer.
Do I still need to validate the output?
The generator produces valid schema.org JSON-LD by construction, so it will not emit malformed markup. It is still worth a quick pass through Google's Rich Results Test on the live page, because that also checks the markup matches what the page actually shows.
