warning Event schema missing required properties (name/startDate/location)
Rule schema.event_incomplete · Structured Data · 1 occurrence(s)
- https://www.tangg134.com/namikaze — Event structured data is missing required property (location) — without them Google won't generate the rich result. Add each field (and validate with the Rich Results Test). It is also missing recommended properties (endDate, offers), which enrich the result.

This is a heuristic (a static-HTML substring check): JS-rendered or abbreviated names can be false positives, so verify before removing.

Rule schema.stale_date · Structured Data · 1 occurrence(s)
