(https://marly.com) 📸 Data Snapshot: May 31, 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.
Structured data is basic Corporation schema with zero sameAs links to social proof or industry certifications. The Person schema identifies jicao as the author, who appears to be a web administrator rather than a chemical engineer or automotive expert, creating a significant authority gap for a technical manufacturer. Technical implementation is poor, with missing H1 tags and a broken heading hierarchy that fails to communicate authority to search engines or users.
The site makes bold claims about cleaning variable turbo geometry and deep FAP regeneration but provides zero case studies or data logs to prove these outcomes. The marketing tone suggests premium, high-tech engineering, yet the actual site demonstrations are limited to product labels and repeated technical blurbs. This creates a distance between the professional performance signal and the thin substance of the evidence.
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.
