Consumer buying behavior refers to how individuals and households purchase goods and services for personal use. There are many factors that influence consumer behavior, including psychological, personal, social, and cultural characteristics. The consumer decision making process involves need recognition, information search, evaluation of alternatives, purchase decision, and post-purchase behavior. Models of this process include stages like awareness, interest, evaluation, trial, and adoption. Business buying behavior differs in that there are fewer but larger business buyers who purchase goods for resale or use in production rather than personal consumption.
