Businesses create value through marketing by building relationships with partners and customers to introduce products, ideas, and services where and when customers want them. They research potential customers, target markets, and competition to understand how to balance benefits and costs for customers and the business. Marketers consider value for customers and society as well as using technology and social media to connect with customers. Constantly balancing customer value and cost while using data to satisfy customer needs builds long-term loyalty. Value is the most important marketing concept according to Philip Kotler.
