Social marketing is the application of commercial marketing principles and techniques to promote socially beneficial behaviors. It aims to influence voluntary behavior change in target audiences to improve personal and public welfare. Formative research is conducted to understand the target audience and factors influencing their behaviors. A strategy is then developed and interventions are designed, implemented, and evaluated to promote acceptance and adoption of the socially beneficial behavior. Challenges to social marketing include a heterogeneous consumer base, expensive media costs, poor execution, and policy decisions that can limit product strategy flexibility. Social marketing in healthcare can influence consumer decision making through reinforcement of messages by trusted healthcare practitioners.
