How to work out net promoter score
The net promoter score is built around 1 question you ask your customers, which is whether or not they would recommend your company or business to others.
The responses are given a rating score between 0 and 10, with 0 being the worst rating and 10 being the best rating.
The categories are promoters, passives, and detractors.
Promoters have scores between 9 and 10 and will tell all their friends about your business. They are loyal consumers who will continue to buy from you and refer other consumers, which result in growth for your company.
