In recent years, the Customer Effort Score (CES) has established itself as one of the most effective metrics for assessing the quality of the customer experience. Unlike more generic indicators such as satisfaction (CSAT) or loyalty (NPS), CES focuses on one fundamental aspect: how much effort a customer perceives in completing an interaction with the company.
According to a study published by Harvard Business Review, reducing customer effort is the most decisive factor in building loyalty. Customers are more likely to come back and recommend a brand when they have simple, smooth experiences, rather than occasional positive surprises.
What is the Customer Effort Score
CES is a quantitative metric based on a very direct question: “How much do you agree with the following statement: The company made it easy for me to complete action X?” The customer answers on a scale from 1 to 5 or from 1 to 7, where 1 means strong disagreement and 5 or 7 full agreement.
The main goal is to measure perceived friction. A low score indicates a complex and frustrating experience; a high score reflects a smooth, easy interaction. In this sense, CES acts as a thermometer of friction across touchpoints.
Why CES makes a difference in Customer Experience
The benefits of CES are backed by hard data. Gartner found that 96% of customers who have low-effort experiences tend to buy again, while only 9% of those who face high-effort interactions show the same intention.
CES has a direct impact on churn, retention and word of mouth. In Customer Care, it is a useful metric for spotting operational inefficiencies, but it is just as strategic in onboarding, checkout and navigation flows.
When and how to measure CES
CES should be collected right after the customer has completed a relevant action: submitting a support request, completing a purchase, using a feature or signing up for a service.
The most commonly used channels are:
- post-interaction micro surveys via email
- in-app or on-site pop-ups
- contextual widgets built into the interface
To get meaningful data:
- use a single, clear question
- adopt standardized rating scales (ideally 1-5)
- contextualize the survey to the action performed
- include an open field for qualitative comments
Interpreting CES results
Once the data is collected, it is useful to calculate the average CES score. However, what matters is identifying where the effort is concentrated:
- by touchpoint (e.g. support, login, purchase)
- by channel (e.g. web, mobile, call center)
- by customer type
Segmentation makes it possible to spot hidden issues and better target corrective actions.
Integrating CES into Customer Journey Mapping
One of the most strategic applications of CES is its integration into Customer Journey Mapping processes. Associating CES scores with the various steps of the journey makes it possible to see where friction is concentrated and to design targeted interventions.
Then, for example, uses this methodology to build advanced dashboards that highlight the highest-effort moments and guide intervention priorities in UX and service design.
Best practices for improving CES
Reducing customer effort means designing frictionless experiences. The most effective practices include:
- Streamline digital flows: simplify navigation and cut redundant steps.
- Proactive, contextual support: chatbots, visual help centers and in-app guides.
- Personalization: show relevant content and calls to action.
- Staff training: empathy and competence reduce perceived effort.
- Omnichannel consistency: prevent customers from having to repeat the same information.
Real examples of using CES
A SaaS platform introduced CES during onboarding and discovered that the initial setup was perceived as too technical. After introducing guided tutorials, the average CES score rose by 30%, with an 18% drop in support requests.
An online retailer analyzed CES in its mobile checkout funnel. Redesigning the payment page led to a 22% increase in conversion rate.
CES, NPS and CSAT: complementary uses
These three metrics should be considered complementary:
- CES: measures the effort perceived in a specific action
- NPS: measures the propensity to recommend the company
- CSAT: measures satisfaction at a given moment
As stated by Qualtrics, combining these metrics gives a complete view of the customer experience. However, CES remains the strongest predictor of short-term loyalty.
Conclusions and call to action
The Customer Effort Score is not just an operational metric: it is a true design mindset. In a context where time is the most precious resource, the winning experience is the one that requires the least effort.
Adopting CES makes it possible to:
- reduce churn
- increase retention
- improve brand trust
- optimize customer service resources
As the Nielsen Norman Group suggests, minimizing user effort is a cornerstone principle of usability. Companies that integrate CES into their design approach manage to build stronger, longer-lasting relationships with customers.
