Marketing is communicating the value of a product, service or brand to customers, for the purpose of promoting or selling that product, service, or brand. Marketing techniques include choosing target markets through market analysis and market segmentation, search engine optimization and branding, as well as understanding consumer behavior and advertising a product’s value to the customer. From a societal point of view, marketing is the link between a society’s material requirements and its economic patterns of response. Marketing satisfies these needs and wants through exchange processes and building long-term relationships. Marketing blends art and applied science (such as behavioural sciences) and makes use of information technology. Marketing is applied in enterprise and organizations through marketing management.
