Quick answer: For AI search visibility, six schema types do most of the work: Organization (who you are), Article/BlogPosting (what you publish), FAQPage (questions you answer), Product with AggregateRating (what you sell and its reputation), LocalBusiness (where you operate) and Person (who writes). Schema converts your pages from text an engine must interpret into facts it can trust – the cheapest confidence-builder in the entire GEO stack.
Why schema matters more to AI than it did to search
Search engines used schema mainly for rich snippets. AI engines use it deeper: retrieval systems disambiguate entities through it, answer generators lift structured facts from it, and knowledge graphs are fed by it. When ChatGPT states your founding year or Perplexity quotes your product rating, structured data is very often the proximate source – unmarked pages force engines to guess, and hesitant engines cite someone else.
The six types, prioritised
1. Organization – sitewide: legal name, logo, url, sameAs to every official profile, contact. The anchor of your entity system.
2. Article/BlogPosting – every post: headline, author (linked Person), datePublished and dateModified. Freshness signals feed retrieval ranking directly.
3. FAQPage – wherever you answer questions: each Q&A pair becomes an extractable answer unit for snippets and AI responses alike.
4. Product + AggregateRating – name, description, price, availability, review consensus. This is how “is X any good” answers find their numbers (product visibility).
5. LocalBusiness – address, hours, geo, priceRange for local answers (local AI guide).
6. Person – authors with jobTitle, worksFor, sameAs: the machine-readable half of E-E-A-T (author bios).
Implementation rules
JSON-LD in the head (or via your SEO plugin), one coherent graph with @id references connecting Organization, Person and Article nodes, values that exactly match visible page content (mismatches erode trust rather than build it), and validation through Google’s Rich Results Test plus the Schema.org validator after every template change.
FAQ
Does schema guarantee AI citations?
No single signal does – schema raises machine confidence, which compounds with content structure and authority. Audit your current coverage in minutes with IndexGraph.ai‘s signal scanner.
Is more schema always better?
No – mark up what genuinely exists on the page. Spammy or false markup risks both rich-result penalties and entity distrust.
