Rich result eligibility

Google's spec for this type

Your WebSite structured data is missing required fields for Google's Sitelinks search box. Without these, the page won't qualify for rich results.

Why this matters

Schema entity missing required properties — Google's rich-result eligibility check fails; the schema is in source but never renders enhanced.
