NPS: relationship and recommendation
Net Promoter Score asks how likely someone is to recommend a company or product. It is most useful for a broader relationship question, with an open follow-up that explains why the respondent chose the rating.
CSAT: the experience just completed
Customer Satisfaction is a direct rating of a recent interaction such as checkout, support, delivery, or setup. Keep the wording tied to that event so the result has a clear operational meaning.
CES: effort in a specific task
Customer Effort Score focuses on how easy or difficult it was to complete a task. It can help teams examine support resolution, onboarding, account changes, or another defined action.
Use the score with the story
A metric is a signal, not a diagnosis. Pair the rating with a short comment, the touchpoint, and relevant context such as location or channel when that information is appropriate and expected.
Compare consistently
If you compare results over time, keep the wording, scale, audience, and timing consistent. Avoid importing industry benchmarks without checking how they were collected and whether the populations are comparable.
