Consumer behavior involves how individuals search for, purchase, use, and dispose of products and services. There are two types of consumers - personal consumers who buy for individual use, and organizational consumers who buy for business use. Marketers have shifted their focus over time from the production concept of making what they can to the marketing concept of determining customer needs. The marketing mix of product, price, place, and promotion aims to create value and satisfaction for customers. Marketers also use digital technologies, customer research, segmentation, targeting, positioning, and relationships to better understand and serve consumers.
