Structured data missing required fields
What this means
A JSON-LD entity omits properties schema.org marks as required for its type, so search engines treat the entity as invalid and skip it entirely.
How to fix it
Add the missing properties using values the page genuinely contains, then confirm with the Rich Results Test — never pad an entity with invented data.
Fix effort
This check needs review: the change can be drafted for you, but a person has to approve the wording or choose the target before it ships.
