1Publish Organization schema (JSON-LD) on the homepage
No Organization-typed JSON-LD detected on your homepage.
Organization schema gives agents a structured representation of your brand identity: name, logo, social profiles, contact info, founding date. Agents use this to verify you are who you claim to be and to link your profile data to a recognizable entity.
