What Is Customer Effort Score (CES)?
Customer Effort Score (CES) measures how easy it was for a customer to get something done — resolve an issue, find an answer, complete a task. Because reducing effort is a strong driver of loyalty, low-effort experiences often predict retention better than satisfaction alone.
Key takeaways
- CES asks how much effort the customer had to expend, on a simple scale.
- Low effort is a strong predictor of loyalty and repeat business.
- It's most useful right after a support or onboarding interaction.
Why effort matters
Research popularized by the “Effortless Experience” found that reducing customer effort drives loyalty more reliably than delighting customers. A frustrating support experience erodes loyalty even if the issue is eventually solved — so measuring effort catches risk satisfaction scores miss.
CES vs CSAT vs NPS
CES is the most operational of the three: it points directly at friction to remove. Use it at high-effort moments — support resolutions, onboarding steps — while NPS tracks loyalty and CSAT tracks satisfaction.
