What a customer satisfaction survey measures
A customer satisfaction survey asks customers how a purchase, visit or conversation went, in a way you can compare over time. Most surveys mix three kinds of scale questions with one or two open questions.
- Satisfaction (CSAT): how satisfied the customer is, usually from 1 to 5. The score is the share of customers who answer 4 or 5.
- Recommendation (the question behind the Net Promoter Score, or NPS): how likely they are to recommend you, from 0 to 10. NPS is the share of 9s and 10s minus the share of answers from 0 to 6.
- Effort (CES): how easy it was to get what they needed. It points to the step that needs fixing.
- Open questions: why they gave the score. They're slower to read but they tell you what to change.
