Customer satisfaction refers to the level of happiness or contentment that customers experience when they interact with a product, service, or brand. It is an important metric for businesses because it measures how well they are meeting their customers' needs and expectations. A high level of customer satisfaction indicates that customers are happy with the products or services they receive, which can lead to repeat business, positive word-of-mouth recommendations, and increased loyalty. On the other hand, low levels of customer satisfaction may indicate that there is a problem with the product or service, leading to dissatisfaction among customers and potentially affecting sales and revenue. Therefore, understanding and measuring customer satisfaction is crucial for businesses in order to improve their offerings and maintain customer loyalty.
