Definition

Structured data is machine-readable information added to pages to clarify entities, relationships, and page meaning.

Expanded definition

Structured data can help search systems understand content, but it cannot compensate for weak copy, outdated claims, or inconsistent positioning. In AEO/GEO, it supports clarity rather than replacing content strategy. The technical layer matters because AI systems need usable context, but technical access is not the same as good interpretation. Clear entities, current pages, consistent claims, and useful source context still determine whether the answer helps a buyer.

Why it matters

Clear structured data can reinforce entity consistency and make important page details easier for systems to parse.

Example

A software page uses structured data to identify the organization, product, FAQ content, and breadcrumbs.

Common mistake

Expecting structured data alone to drive AI answer inclusion or favorable framing.

Diagnostic question

Does structured data reinforce the same entity, category, and page meaning that the visible content communicates?
