Consumer behavior is the study of how consumers make purchase decisions and how firms can influence those decisions. It involves understanding how consumers think, feel, reason, and select between different brands and products. Consumer behavior is influenced by culture, family, and media. Studying consumer behavior helps firms develop effective marketing strategies by gaining insights into why consumers purchase products, when they purchase, and how they prefer to shop. An understanding of consumer behavior allows companies to segment markets, target specific groups, and make appropriate marketing mix decisions regarding product, price, place, and promotion.
