Schema.org defines hundreds of types (from Movie to Recipe to ExercisePlan), but for most sites only a few types have a real impact on how an AI engine understands you. Here's where it's worth spending your time.
The high-impact types
- Organization: official name, logo, sameAs (links to social/directory profiles) — the foundation of brand "identity" for an engine.
- WebSite: explicitly declares the domain as an entity, useful for entity linking.
- FAQPage: explicit questions and answers, often extracted nearly verbatim by generative engines.
- LocalBusiness (and subtypes like
Hotel,Restaurant,ProfessionalService): address, hours, price range — essential for local queries. - Product: price, availability, reviews — for e-commerce, the type with the most direct impact on purchase prompts.
- Article/BlogPosting: publish date and author, useful signals for content freshness and provenance.
The types that rarely earn their keep (for AEO)
Very niche types or ones built for specific visual rich snippets (e.g. Recipe on a site that isn't about cooking, Course with no real course catalog) add maintenance complexity without a proportional benefit for AI citation, unless they're your actual core business.
A mistake to avoid: schema that contradicts visible text
Declaring a price or hours in JSON-LD that differ from what users see (often because the schema wasn't updated when the site changed) is worse than having no schema at all: an engine that detects the mismatch loses trust in all structured claims from that domain.
Our free schema.org generator creates Organization and WebSite markup from your site's real content, avoiding this exact risk.
