Customer Effort Score (CES)
A metric that measures how easy it was for a customer to accomplish a specific task or resolve an issue, typically on a 1-7 scale from "Very Difficult" to "Very Easy."
Also known as: CES
Why It Matters
Research shows that reducing customer effort is a stronger predictor of loyalty than delighting customers. Customers who find your product or support easy to use are far more likely to stay, expand, and refer others.
CES is most valuable when measured after specific interactions - completing a task, using a feature, or contacting support. It gives you targeted, actionable feedback about friction points.
How to Track in KISSmetrics
Trigger CES surveys in KISSmetrics after key interactions. Track the score as an event property tied to the specific feature or action. Compare CES across different product areas to prioritize UX improvements.
Common Mistakes
- -Only measuring CES for support interactions, missing product friction
- -Surveying too broadly instead of after specific tasks
- -Not acting on the results - CES is only valuable if you fix the friction it reveals
Pro Tips
- +Combine CES with NPS for a complete picture: CES shows tactical friction, NPS shows strategic satisfaction
- +Measure CES at onboarding milestones to identify where new users struggle most
- +Track CES trends after product changes to validate UX improvements
