The same word should not mean something different on every page.
The formal definitions governing Search Intelligence.
SI works across Marketing, SEO, Technology, Product, Risk, Finance, Governance and AI. Many of these disciplines use similar words differently.
The Formal Definitions Library establishes the approved SI meaning, relationship and boundary for each canonical term.
Why controlled definitions matter
Search Exposure is not the same as a Search Encounter.
A Search Encounter is not automatically a Search Moment.
Search Intelligence is not Search Governance.
Search Governance does not control the external market.
Organic Marketing is not another name for SEO.
AI Visibility is not AI Narrative Integrity.
Modelled value is not validated value.
Definition structure
Where relevant, each term should show:
Canonical name

Plain-language explanation
Architectural position
Inclusions
Exclusions
Related terms

Governance implications
Approved shorthand
Version
Effective date
Superseded terminology
Controlled collections
Architecture
Customer progression
Evidence and confidence
Growth and demand

Governance and value
The definitions are authoritative within the SI architecture. They should not be presented as universal industry standards or as having been adopted by an external regulator or professional body.
