To understand how consumers actually make their buying decisions, marketers must identify who makes and influences the buying decision. People can be initiators, influencers, deciders, buyers, or users, and different marketing campaigns might be targeted to each type of person. Marketers must also examine buyers’ levels of involvement and the number of brands available to determine whether consumers are engaging in complex buying behavior, dissonance-reducing buying behavior, habitual buying behavior, or variety-seeking buying behavior.
