Abstract
Consumer behaviour is an important area of marketing management because every marketing decision ultimately depends on understanding how consumers think, feel, compare and choose. The present research paper examines consumer behaviour from a marketing perspective, with special attention to the factors that influence buying decisions and the changing behaviour of Indian consumers in the digital environment. Consumer behaviour includes the activities involved in selecting, purchasing, using and evaluating products, services, ideas and experiences. The study explains cultural, social, personal and psychological influences, along with situational and technological factors. It also discusses the five major stages of the consumer decision-making process: need recognition, information search, evaluation of alternatives, purchase decision and post-purchase evaluation. The paper uses secondary research from academic marketing texts, professional marketing sources and recent Indian e-commerce reports. The findings show that consumers are no longer influenced only by price and product features. Reviews, convenience, social influence, brand trust, digital content, payment options, delivery experience and post-purchase service increasingly shape purchase decisions. In India, the expansion of smartphones, internet access and e-commerce has made the consumer journey more connected across online and offline channels. For marketers, this means that understanding the consumer is not a one-time activity; it is a continuous process of observing needs, reducing uncertainty, creating value and maintaining relationships after purchase.
