Six schema types, the ones AI engines actually quote.
Schema is the cheapest edge left in modern search. About 88% of sites still skip it. Use this tool to close the gap on the pages that matter.
Every site. The canonical company record AI engines pull when they answer about your brand.
Every blog post or long-form article. Drives the title, author, and date inside AI Overviews.
Pages with FAQ sections, glossaries, or any Q+A structure AI engines can lift verbatim.
Tutorials and walkthroughs with ordered steps. The schema HowTo most often gets cited inside AI Overviews.
Product detail pages. Drives price, availability, and rating snippets across Google and AI shopping assistants.
Every interior page. Cheap to ship and consistently improves how Google renders your URL in the SERP.
Four steps from blank to validated.

Paste it in your page head and validate
Drop the block inside the <head> of the matching page. Validate at validator.schema.org and Google's Rich Results Test before deploying.
Schema is one layer. Brand Hub plus llms.txt is the rest.
JSON-LD on every page gives AI engines clean facts to quote. Brand Hub plus llms.txt gives them a canonical source to trust. Together they install the AEO foundation.
Frequently asked questions
What teams ask before they ship Schema.org JSON-LD.
- 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.
- 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.
- Inside the <head> of the matching page, wrapped in a <script type="application/ld+json"> 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.
- 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.
- 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.
- 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.
- Yes. A blog post page typically ships BlogPosting plus FAQPage plus BreadcrumbList. A product page typically ships Product plus BreadcrumbList. Use one <script type="application/ld+json"> block per type.
