The marketing conversation around AI is shifting from how brands can use it internally to how they can reach people who are using it to make decisions. In the IAB study covered by Forbes, adapting to changing consumer behavior, including AI-driven search, was the top media-investment challenge for 44% of buyers.
Optimizing content for AI-generated answers was also the largest area of increased focus, cited by 76% of buyers. Measurement isn’t keeping pace. Buyers are changing how they evaluate performance, but many still struggle to connect AI-shaped journeys with the channels and metrics they already use.
That creates a measurement problem for healthcare brands. Patients, HCPs and other stakeholders may encounter information about a brand inside an AI-generated answer without visiting the source or entering a trackable website journey. That makes visibility, citation quality and answer accuracy important measures alongside traffic. It also means GEO can’t sit only with digital teams. Earned, medical, advocacy, corporate and owned content can all shape the information AI systems retrieve and use.
