Which model emphasizes the sequential steps a consumer takes from awareness to purchase?

The Hierarchy of Effects model is the correct choice because it systematically outlines the stages a consumer typically goes through in their decision-making process, progressing from awareness and knowledge of a product to forming feelings, preferences, and ultimately making a purchase. This model breaks down the consumer journey into distinct stages, emphasizing the importance of each step in guiding potential customers from being unaware of a product to actively choosing to buy it.

In this model, marketers focus on how to move consumers through these stages, often using various marketing strategies tailored to each step. By understanding this sequential flow, marketers can develop more effective communication strategies that address consumers' needs at each point in their decision-making process.

The other models, while relevant to consumer behavior, do not specifically emphasize this sequential journey as clearly. The Behavioral model focuses more on the actions of consumers based on stimulus-response theories without outlining the stages leading to purchase. The Affective model centers on the emotional responses consumers have towards products, which can influence their decision-making but doesn't structure the process into clear sequential steps. The Innovation Adoption model relates specifically to how consumers adopt new products over time but does not cover the broader journey from awareness to purchase.
