グランスタ (Gransta)
(https://gransta.jp) 📸 Data Snapshot: May 30, 2026Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.
The primary authority gap is technical: the schema_json is null across the board, which is a missed opportunity for an official facility to assert its identity via Organization or LocalBusiness markup. There are no claims of individual ‘experts,’ as the authority is derived from the brand ‘Tokyo Station / TOKYOINFO.’ The presence of unrendered curly-brace placeholders on the search page (Slot 1) slightly undermines the ‘official’ technical credibility.
The site makes very few performance claims, focusing instead on operational facts. The claim that ‘limited sweets No.1 has been decided’ is backed by a specific dated ranking (2025.07.03), showing a clear connection between the claim and the editorial process. There is no disconnect between the marketing tone (which is helpful and informative) and the actual data provided.
Identity & Authority is read from the structured data first: whether the site declares who it is in machine-readable schema, with verifiable identity links. Below is the schema captured per page, then the external proof links that support (or fail to support) that identity.
