Quick take

If you want to know how easy or difficult something was for users, measure it with CES.

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 , such as completing a purchase, resolving an issue, or finishing a task.

Unlike CSAT, which measures satisfaction, CES focuses specifically on effort. It is based on the idea that reducing effort to better experiences and higher .

The goal is to identify and make as simple and seamless as possible.

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

It is most useful when:

You want to measure how easy a process feels

It is less useful when:

You need broader sentiment or satisfaction insight
The interaction is not clearly defined
Context around the score is missing
CES is often used alongside CSAT and usability testing to combine measurement with deeper understanding.

Key takeaway
