Serokell
(https://serokell.io) 📸 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 well-established through detailed schema including ‘sameAs’ links to GitHub, LinkedIn, and YouTube. Blog posts are attributed to specific, named experts like Diogo Castro and Ivan Smetannikov, providing a clear digital footprint. The technical implementation, including a clean heading hierarchy and proper JSON-LD, matches the firm’s claim of technical excellence.
There is a minor disconnect in the claim of serving ‘1B of users globally,’ which is a round, unverified number in the meta description. However, most other performance claims, such as ‘predicting time-to-failure in electric locomotive engines,’ are tied to specific, named projects in the portfolio, reducing the overall BS level.
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.
