Expanded definition
Schema markup can help clarify page context for search systems. It is useful when it matches the visible content and reinforces consistent entity understanding. 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
Schema can support interpretation, but misleading or thin markup will not solve a weak content or source-influence problem.
Example
A glossary page uses schema-relevant structure, breadcrumbs, and clear definitions that match the visible article.
Common mistake
Adding markup without fixing vague definitions, inconsistent naming, or outdated page content.
