What does Structured Data mean?
Structured data is standardized markup — most commonly JSON-LD using the schema.org vocabulary — that tells search engines and AI systems what content represents: an article, a product, an FAQ, an organization. It makes meaning explicit instead of leaving it to be inferred from text.
Why does it matter?
Structured data helps a machine parse entities and relationships on the page, and it is required for eligibility for many rich results. It does not guarantee enhanced listings.
What does it look like in practice?
A glossary page marks each definition as a DefinedTerm inside a DefinedTermSet, so an engine can map the term, its meaning, and its URL without guessing.
Frequently asked questions
Does structured data improve rankings?+
Google states structured data is not a direct ranking factor. It helps machines understand the page and unlocks eligibility for enhanced result features.
Should I mark up everything?+
No. Markup that misrepresents content or spams irrelevant types can be ignored or trigger manual actions. Mark up what is actually on the page.
