Within Stacy Nelson’s 4 C’s of External AI Readiness framework, each C is intentionally paired with a related optimization discipline:
Compatibility = Agentic Commerce Optimization (ACO), focused on fit, commerce data, and agentic transaction readiness.
Clarity = Answer Engine Optimization (AEO), focused on making information easy to retrieve, understand, and answer.
Credibility = Generative Engine Optimization (GEO), focused on authority, citations, third-party validation, and trust.
Consistency = Brand Context Optimization (BCO), focused on aligned facts and brand context across the wider digital ecosystem.
These pairings provide a clear way to organize the framework, while acknowledging that the disciplines overlap in practice.
