CES measures the effort a customer spent to get something done—why effort beats satisfaction at predicting loyalty, and where to ask it.
CES asks how easy it was to accomplish a task—typically "How much effort did you personally have to put forth?" on a 1-7 scale. Research consistently links low effort to repeat behavior, often more tightly than satisfaction does.
CES = mean effort rating (1-7); report % "low effort" (top 3 boxes).
Onboarding CES 4.9 → the certificate-retrieval flow takes three logins; fixing it moved repeat usage more than the whole satisfaction push.
After every task with friction potential: onboarding, renewals, support, refunds. Pair with one open "what made it hard?"
Don't ask CES on relationship moments—it measures tasks. And low effort with bad outcomes just makes leaving convenient.
CSAT rates how they feel, CES rates how hard you made them work. Optimize CES on transactional journeys, CSAT on experiences.
7-point is standard and more sensitive; keep the same anchors every cycle.
