Customer Effort Score (CES)
A practical measurement method for understanding perceived effort in key journeys and interactions.
How to use CES to measure effort, identify friction in task completion, and simplify the experience over time.
What it is
Customer Effort Score (CES) is a UX and product metric used to measure how much effort a user had to put in to complete a task.
It typically asks a question such as “How easy was it to complete this task?” with a rating scale.
CES is usually triggered immediately after a key glossaryInteractionInteraction refers to any action a user takes within a product and how the system responds.

CES is useful when you want a direct measure of how hard the experience feels from the user’s point of view.
When to use it
Use this method when glossaryUsabilityUsability is how easy and efficient it is for users to complete tasks within a product. It focuses on clarity, simplicity, and reducing effort so users can achieve their goals without confusion or friction.Open glossary term is critical.
It is most useful when:
It is less useful when:
CES is often used alongside CSAT and usability testing to combine measurement with deeper understanding.
Key takeaway
Use CES when the main question is how hard the interaction feels and where effort can be reduced.
How to run it
Set up properly
Be clear on the glossaryInteractionInteraction refers to any action a user takes within a product and how the system responds. It includes clicks, taps, gestures, and inputs that drive the user experience.Open glossary term you are measuring, when the question fires, and which scale you are using. Effort is specific. Asking about the whole relationship produces an average of nothing.
Word the question carefully. Effort questions are unusually sensitive to phrasing, and reversing the direction of the scale is a common and silent error.
Run the method

It is often a better predictor of loyalty than satisfaction, because people forgive an average experience and resent a laborious one.

- Use a consistent scale, and make sure high and low are unambiguously labelled so nobody answers backwards.
- Trigger immediately afterwards, while the effort is still felt rather than remembered.
- Include an optional open follow-up asking what was hardest. That answer is where the fix usually is.
- Keep it quick and unobtrusive, and avoid asking after every glossaryInteractionInteraction refers to any action a user takes within a product and how the system responds. It includes clicks, taps, gestures, and inputs that drive the user experience.Open glossary term.
