Detailed explanation of customer experience metrics - how much do you know about customer satisfaction, customer effort score, and net promoter score?
Blogs
In the field of customer experience management, there are three core metrics—Customer Satisfaction (CSAT), Net Promoter Score (NPS), and Customer Effort Score (CES)—that provide businesses with important tools for a comprehensive evaluation of user experience. Each metric has its unique characteristics and together they form a complete monitoring system for customer experience.
1. Customer Satisfaction (CSAT)
CSAT uses a five-point scale (from ‘very dissatisfied’ to ‘very satisfied’) to collect users’ immediate feedback on specific service interactions or experiences. Its greatest advantage lies in its ease of use and flexible application scenarios: businesses can quickly set up CSAT questions to measure after users complete key operations (such as logging in) or finish customer service consultations.

Best practices indicate that effective CSAT measurement needs to pay attention to three points:
The question design should be concise and clear, and completion time should be within three minutes.
Increase user participation through incentive rewards or lottery mechanisms.
In addition to collecting numerical values, it’s essential to delve into the underlying reasons for satisfaction/dissatisfaction, that is, what factors cause users to feel satisfied or dissatisfied with a product or service? What are the relationships or weights of these factors? And how can we improve to make users more satisfied?
It is important to note that CSAT may have a central tendency bias in practical applications, where users tend to choose neutral scores. Therefore, businesses need to combine qualitative analysis to explore the driving factors and weighting relationships behind the scores.
2. Net Promoter Score (NPS)
NPS divides customers into three categories through a question—“How likely are you to recommend the XX product or company to a friend or colleague?” (0-10 points)—: Detractors (0-6 points) are dissatisfied or lack loyalty, Passives (7-8 points) are generally satisfied but not very loyal, and Promoters (9-10 points) are satisfied and loyal, willing to continue purchasing and recommending to others. The Net Promoter Score (NPS) = (Number of Promoters/Total Sample Size) × 100% - (Number of Detractors/Total Sample Size) × 100%, in simple terms, is the percentage of Promoters minus the percentage of Detractors.

Industry practices show:
An NPS score above 50% is considered good.
A score of 70-80% indicates a high loyalty customer base.
Most companies have an NPS score between 5-10%, showing significant room for improvement.
The advantage of NPS is that it asks about willingness rather than sentiment, making it easier for users to respond. Its results are more intuitive and predictive, reflecting a company's development trends and sustainable profitability. However, it should be noted that NPS cannot completely replace satisfaction surveys; companies should consider it as part of the customer experience management system. Data shows that improving CSAT scores will directly promote NPS score growth.
3. Customer Effort Score (CES)
CES was proposed in 2010 by the Harvard Business Review to assess the difficulty customers face in using a product or service to solve problems. There are currently two mainstream versions:
Original version: Directly asking “How much effort did you expend to get the service you wanted?” (1-5 points)
Improved version: Using a Likert scale to measure the level of agreement with “The company made my problem-solving process simple.”
Research indicates that Customer Effort Score has a negative correlation with loyalty: the lower the effort, the higher the loyalty. This metric reminds businesses that, rather than just pleasing customers, it is more important to reduce the effort customers expend during consumption, providing hassle-free products and services.

Comprehensive Application Suggestions
Wise companies adopt a multi-dimensional metric evaluation system:
CSAT monitors the immediate experience at specific touchpoints.
NPS tracks overall customer relationships and long-term loyalty.
CES optimizes service processes and user experience design.
Using all three metrics together, businesses can gain comprehensive insights into customer experience while providing targeted guidance for improvements across different departments. By continuously monitoring and analyzing these metrics, companies can build a more scientific and efficient customer experience management system, ultimately achieving a positive cycle of business growth.
