User satisfaction refers to the degree to which users feel their needs and expectations are met when interacting with a product or service. It is often measured through surveys, feedback forms, and ratings, providing valuable insights into how well a company or organization is performing. High user satisfaction typically leads to increased loyalty and positive word-of-mouth. Factors influencing user satisfaction include usability, functionality, and customer support. For example, a well-designed website or app can enhance user experience, while responsive customer service can address issues promptly. Companies like Amazon and Apple prioritize user satisfaction to maintain their competitive edge in the market.
