Identity & Authority — The Lens

Inspect 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.

A significant technical authority gap exists as schema_json is null across all audited pages, meaning the site fails to communicate its professional entities (Person or SportsOrganization) to search engines programmatically. While Sergio Coyle Diez is clearly the central authority, there is no Person schema or sameAs links to his official PGA credentials or social proof. Additionally, the meta_description is empty for the homepage, reflecting a lack of technical optimization for a ‘leading’ professional.

The site makes several bold performance claims in the ‘Milestones’ section regarding ‘Championship Wins’ and ‘International Honours’ but provides no specific list of dates or event names to anchor these claims. The blog content demonstrates high expert knowledge, yet the disconnect between the claim of ‘Milestones’ and the actual display of those milestones (which are currently just empty headings) creates a substance gap. Most other technical claims regarding the use of ‘Bull 3D’ and ‘Force Plates’ are well-demonstrated through instructional context.

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.
