The marketing concept is an approach that places the customer at the center of all marketing activities. It is a customer-centric approach that focuses on identifying and satisfying customer needs and wants. Instead of just promoting and selling products or services to customers, the marketing concept aims to build long-term relationships with customers by understanding their needs and providing products or services that meet those needs. By adopting the marketing concept, companies can create more value for customers and ultimately achieve greater success in the marketplace.
