Schema Markup is one of the technical foundations of AEO. It uses standardized formats (JSON-LD) to tell search engines and AI systems what your page content is — whether it's an article, product, FAQ, or business entity.
Particularly important Schema types for AEO include: FAQPage (frequently asked questions), HowTo (how-to guides), Organization (business information), Product (product information), and Article. Proper Schema markup can increase your chances of being cited by AI by up to 40%.
