What Is Customer Effort Score (CES)?
CES measures how easy it was for a customer to get their issue resolved. Low effort is a stronger predictor of loyalty than high satisfaction.
Key Takeaways
- CES asks: how easy was it to resolve your issue today?
- High effort predicts churn more reliably than low satisfaction alone
- CES is most useful for evaluating support interactions and checkout processes
- Reducing effort across touchpoints is often more impactful than adding wow moments
What CES is
Customer Effort Score measures how much effort a customer had to expend to get something done — resolve a problem, complete a purchase, or get a question answered. The survey typically asks: how easy was it to handle your issue today, on a scale of 1 to 7? A low score (high effort) is a strong predictor the customer will not return.
Why effort matters more than delight
Research from the Corporate Executive Board found that reducing customer effort is a more reliable driver of loyalty than exceeding customer expectations. Customers rarely remain loyal because of a wow experience — they leave because of a painful one. Fixing friction that causes high effort is more impactful for retention than investing in moments of delight.
When to use CES
CES is most useful at specific service or journey touchpoints: after a customer service interaction, after a purchase or returns process, and after onboarding. It is less useful as an overall brand metric — for that, NPS is more appropriate.
CES vs CSAT vs NPS
CSAT asks: how satisfied were you with this interaction? It measures satisfaction with a specific event. CES asks: how much effort did that take? It measures ease. NPS asks: how likely are you to recommend us? It measures overall loyalty. Mature CX programmes use all three in complementary ways.
Reducing effort in practice
Common high-effort points in eCommerce: returns processes requiring printing a label and boxing goods rather than a self-service portal; checkout processes with too many steps or mandatory account creation; customer service requiring customers to repeat information to multiple agents. Identify your three highest-effort touchpoints and invest in reducing friction at each one.
