TEIN (株式会社テイン)
(https://tein.co.jp) 📸 Data Snapshot: May 25, 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 authority is grounded in institutional manufacturing expertise rather than individual ‘gurus.’ While the schema_json is relatively basic (WebPage/WebSite), the technical implementation of the product search and fitment database indicates a high degree of technical credibility. There are no unverifiable expert claims; instead, the authority is proven through technical specifications and a 3-year/60,000 km warranty backed by a listed repair protocol.
Performance claims are consistently backed by engineering data. The claim of ‘1.5 times tensile strength’ over stock parts is supported by a comparative table showing Mpa values for both OEM and TEIN products. The claim of ‘superior anti-rust performance’ is backed by a patent reference and a description of the 2-coat-1-bake powder coating process. The disconnect between marketing tone and technical demonstration is non-existent.
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.
