An NPS detractor is an individual or organization that expresses negative sentiment towards a company or brand, specifically in regards to their Net Promoter Score (NPS). This score is a measure of customer satisfaction and loyalty, and detractors are those who rate the company or brand with a score of 6 or below on a scale of 0-10. These individuals or organizations are not likely to recommend the company or brand to others and may actively discourage others from using their products or services. NPS detractors can have a significant impact on a company’s reputation and success, making it crucial for businesses to address and resolve their concerns in order to improve their overall NPS.
