Your NPS is the accumulation of people who use your product or service taking the time to rate whether or not they would recommend your product or service to others. Based on the score they give your product or service, they fall into one of three buckets:
• Detractors: People who rate you from 0-6 and are supposedly unsatisfied with your product and may cause brand damage
• Passives: People who rate you from 7-8 and don't seem to have any strong feelings for your product, meaning competitive products could sway them.
• Promotors: People who rate you between 9-10 and are your biggest fans. They are likely to be loyal to the brand, repurchase, and help spread the (positive) word.
