FAQ

Does schema markup directly improve rankings?

Schema helps search engines understand entities and page meaning, but adding markup alone does not guarantee higher rankings or rich results.

Should schema describe content that is not visible on the page?

No. Structured data should accurately represent the visible page and should not invent reviews, claims, people, products, or other entities.
