What schema types does the builder cover?

Organization, Article (BlogPosting), FAQPage, HowTo, Product, and BreadcrumbList. These are the six types that drive the most AEO and SEO lift in 2026 and the ones AI engines quote most often.

Does the tool send my data anywhere?

No. Everything runs in your browser. Nothing is sent to a server, nothing is stored, nothing is logged. Refresh the page and your inputs are gone.

Where do I paste the generated JSON-LD?

Inside the of the matching page, wrapped in a tag (the builder wraps it for you by default). One block per page, one type per block. Some types like FAQPage and BreadcrumbList can co-exist with the Article block on the same page.

How do I validate the output?

Paste it into validator.schema.org for raw schema.org validity, then run it through Google's Rich Results Test to confirm Google can render the rich snippet for that page. Both are free and take under a minute.

Why does AEO need schema?

AI engines retrieve facts. Schema gives them clean, labeled facts they can lift verbatim. About 88% of sites still skip it. That gap is one of the cheapest edges left in modern search. See our AEO 101 guide for the full case.

Should I use schema-dts or write JSON-LD by hand?

If you ship in TypeScript, schema-dts gives you compile-time type safety. If you ship in plain HTML or any CMS, hand-written JSON-LD (or this builder) is fine. The output is identical from a search-engine perspective.

Can I use multiple schema types on one page?

Yes. A blog post page typically ships BlogPosting plus FAQPage plus BreadcrumbList. A product page typically ships Product plus BreadcrumbList. Use one block per type.
