Schema Markup

Definition

Schema markup is a vocabulary of tags, defined at schema.org, that you add to a page's HTML to label its content as structured data. Common types for AEO include Article, FAQPage, and DefinedTerm, each helping engines understand and reliably extract specific parts of a page.

Why it matters for AEO

Schema markup helps answer engines parse and trust your content by removing ambiguity about what each element is. Marking up definitions, FAQs, and articles makes them easier to extract accurately. It supports citation but does not replace clear, answer-first writing and crawlable pages. Validate your markup and match the schema type to the page's actual content, since inaccurate or mismatched markup can do more harm than good.
