Consumer behavior is the study of how people choose, buy, and use products and services. It looks at what influences these decisions, including cultural, social, personal, and psychological factors. Understanding consumer behavior helps marketers create better strategies to reach and satisfy their target audience. Marketers use consumer behavior insights to develop products, set prices, create ads, and choose where to sell. They also use various research methods like surveys and focus groups to gather data. By applying this knowledge, companies can better meet consumer needs and build strong customer relationships.
