Net promoter score (NPS) is a customer experience metric for gauging customer loyalty and customer satisfaction. NPS is tracked by a variety of business types, from internet service providers to financial services, and can even be used to assess the satisfaction of employees at a company. Typically, net promoter scores are determined through single-question customer feedback surveys that ask how likely an individual would be (on a scale of 1–10) to recommend a business’s products or services to a colleague or friend.
