A net promoter score is a customer satisfaction metric that measures how likely a customer is to recommend your solution. This data is usually collected using a survey. Based on the rating they give, a customer is either considered a detractor (wouldn’t buy the solution again or recommend it), passive (satisfied but wouldn’t necessarily promote the solution), or a promoter (a repeat buyer that acts as a brand ambassador). Some industries use a scale of 0-10, while others use 0-100.
