What Is Customer Effort Score?
Customer Effort Score (CES) measures how easy it was for a customer to accomplish their goal — getting an answer, resolving an issue, completing a purchase. It is typically measured with a single question: On a scale of 1-7, how easy was it to handle your issue?
Research from the Corporate Executive Board found that reducing customer effort is a stronger predictor of loyalty than increasing satisfaction or delight.
Why Effort Matters More Than Delight
Customers do not want to be wowed. They want things to work. A low-effort experience — where issues are resolved quickly, self-service works, and agents are empowered — drives repeat business more reliably than occasional moments of delight.
How to Measure CES
Send a CES survey immediately after a support interaction, self-service session, or key product action. Keep it to one question plus an optional comment. Response rates drop sharply with longer surveys.
Reducing Customer Effort
- Build comprehensive self-service so customers can help themselves
- Reduce the number of contacts needed to resolve an issue
- Empower agents to solve problems without escalation
- Proactively communicate before customers need to ask
- Eliminate channel switching — resolve in the first channel the customer uses
CES in Practice
Track CES by channel, issue type, and customer segment. Compare CES for AI-assisted vs. human-only interactions. Use low CES scores as triggers for process improvement projects.
