Schema Health
Schema health refers to whether structured data is present where it should be, correctly mapped to the visible content, technically valid, and consistent across related pages. Healthy schema reduces ambiguity and supports stronger machine understanding.
Good schema health is not about using the maximum number of types. It is about using the right markup in the right places with the right relationships.
Poor schema health often shows up as gaps, mismatches, stale values, or markup that no longer reflects the visible site.
