有限会社ＳＳＫ (SSK Co., Ltd.)
(https://ssk.co.jp) 📸 Data Snapshot: May 24, 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.
Authority is partially established by the inclusion of a specific license number (Second-class architect office No. A-78101), but this is undermined by the total lack of technical schema or Person-based structured data. The representative, Tetsuya Sakagami, is named but has no digital footprint linking him to the professional claims made on the site. The technical execution is poor, characterized by duplicated H2 tags and a complete absence of JSON-LD, which is ironic for a firm claiming ‘Digital Marketing’ as a core service.
The site’s timeline claims a continuous evolution from 1992, including specific milestones like ‘Web Analyst Instructor Certification’ in 2016. Despite these claims of expertise, the site itself demonstrates zero digital marketing proficiency, failing even to provide meta descriptions or a coherent heading hierarchy. This creates a performance disconnect where the firm’s claimed capabilities are directly refuted by its own digital presentation.
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.
