Structured Data
Optimus Pass Glossary · Last updated August 29, 2026
Definition
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 it matters
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.
Practical example
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.
