What public signals help to identify a company as a unique entity?
Companies should maintain a shared identity core consisting of their official name, alternative names, domain, locations, identifiers, and services. While the website, organization markup, and relevant profiles reflect the same facts, the internal representation of an LLM remains not directly controllable.
Entity fusion
Entity fusion Similar names and unclear profiles can mislead users into misattributing services or individuals to another company.
Invented authority – Inaccurate sameAs, founder, or partner relationships create new false signals instead of clarity.
Rebranding Inconsistency – A brand change without documented relationships makes old and new names appear as separate organizations.
Documented Relationship
An entity register records names, URLs, IDs, relationships, time periods, and authoritative public evidence.
Custom pages, markup, and auditable profiles are checked against the register and updated without inconsistencies.
AI false statements are logged with context and addressed first in cases of identifiable public source conflicts.
Stable Identifier
Test criterion
Stable Identifier
Official domain, organization URL, and available unique identifiers remain correctly linked across sources.
Test criterion
Documented Relationship
Brand, parent company, product, person, and location are linked only where the relationship is publicly accurate.
What Sets Us Apart Entities with the same name or previous entities are clearly distinguished by location, industry, time period, and official references.
Practical Scenario: Entity Merger
A brand continues to operate after an acquisition, but some profiles incorrectly list it as an independent company. Official pages and markup correctly describe the brand, owner, and time period without removing the old identity from historical records.
