What Is Customer Effort Score (CES)?
Customer Effort Score measures how much effort a customer had to expend to resolve an issue or complete a task. Research from Gartner shows that reducing customer effort is a stronger predictor of loyalty than delighting customers. In other words: "easy" drives retention more reliably than "amazing."
The CES Question
The standard CES question: "The company made it easy for me to handle my issue." Respondents answer on a 1–7 scale from Strongly Disagree to Strongly Agree. High scores = low effort = good. CES = average of all responses. Some companies use a simpler "How easy was it?" 1–5 scale.
CES vs NPS vs CSAT
CES is best measured immediately after a specific interaction (support, checkout, returns). NPS measures long-term loyalty. CSAT measures overall satisfaction with an interaction. CES is particularly valuable for identifying process friction — it tells you where your operations are making customers work too hard.
How to Reduce Customer Effort
Identify the touchpoints with the lowest CES scores. Common causes of high effort: having to contact support multiple times for the same issue (channel hopping), needing to repeat information across agents, unclear instructions in onboarding flows, and difficult returns or cancellation processes. Fix the top 3 systematically before measuring again.
