What Is Customer Effort Score & How to Use It Effectively?

Customers rarely complain when an experience requires too much effort. 

They simply stop coming back.

Every extra click, form field, or confusing step adds friction to the user experience.

Over time, that friction quietly erodes loyalty, retention, and repeat behavior.

Customer Effort Score (CES) helps you measure how easy or difficult an experience feels from the customer’s perspective.

In this guide, we’ll break down what Customer Effort Score is, why it matters, how to measure it, and actionable strategies you can use to reduce customer effort across key touchpoints.

What is customer effort score?

The concept of Customer Effort Score (CES) was introduced in a study by the Corporate Executive Board (CEB), which Gartner later acquired. 

At its core, CES answers one question: 

“How easy was it to resolve your issue or complete your task?” 

Users can choose from a range of values, indicating very easy to very difficult.

CES is a key customer experience metric that measures how much effort customers had to put in to complete an interaction, resolve an issue, or perform an action.

Why is customer effort score important?

When interactions feel difficult, customers are less likely to return, even if the product or service itself is strong.

Instead of asking customers whether they’re “satisfied,” Customer Effort Score focuses on the level of effort they had to put in. 

It helps teams pinpoint where “effort” is creeping into the user journey so they can prioritize improvements more effectively. Let’s understand why CES is important to improve customer experience:

1. Identify drivers of customer loyalty and retention

When customers struggle to complete basic tasks like tracking an order, getting support, or finding pricing details, they’re less likely to stay, regardless of the outcome.

By tracking effort for these tasks, teams can focus on removing friction that impacts user experience and long-term loyalty.

2. Catch early signals of potential churn

A high customer effort score is a leading indicator that something in the customer experience is broken, which could be:

• Confusing navigation
• Slow support response
• Clunky checkout
• Bugs in product workflows

It helps you identify early signs of friction so you can fix them before they compound.

Every element on your website sends a signal about whether your brand is trustworthy, relevant, or worth engaging with. Sometimes those signals are clear, but at other times they simply create confusion that pushes visitors to look elsewhere. The real challenge is identifying these moments across the digital journey and understanding the deeper reasons behind them.

3. Get context beyond satisfaction scores

If the user experience feels heavier or more time-consuming than what customers are used to, they will leave.

CES helps you benchmark whether you’re keeping up with these rising expectations.

4. Improve operational efficiency

By identifying high-effort interactions, CES enables businesses to avoid costly repeat interactions and optimize self-service options, which often leads to:

• Higher conversions
• Fewer abandoned flows
• More repeat purchases
• Stronger lifetime value

When to use customer effort score?

Customer Effort Score works best when measured at moments when customers are trying to complete a task.

Here are the most effective scenarios to deploy a customer effort score survey:

1. After a support interaction

This is the most common and high-impact use case. It measures the ease of resolving issues and enables organizations to improve support team efficiency and training.

Typically, CES surveys are deployed immediately after:

• Chat or email support conversations
• Phone interactions
• Resolution of a support ticket

2. After completing a key product task

For SaaS and digital products, CES is usually triggered after tasks like:

• Free trial or demo signup
• Onboarding completion
• Subscription plan changes
• Third-party tool integration
• In-product workflow completion

3. After a purchase or transaction

Gauge how easy or challenging the checkout process was to identify and fix issues that may lead to cart abandonment. 

eCommerce marketplaces often deploy CES surveys to measure effort during key tasks, such as:

• Browsed products
• Added items to the cart
• Completed payment
• Tracked orders or returns

4. After using self-service or help center resources

Teams also deploy CES surveys when customers:

• Search the knowledge base
• Browse FAQs
• Interact with chatbots
• Attempt troubleshooting on their own

If customers still contact support after these interactions, you can make targeted improvements to improve the quality and scale of your self-service resources.

5. During renewal, cancellation, or plan changes

Renewal or cancellation is a complex and emotionally charged process. CES helps you understand whether the experience felt:

• Transparent
• Simple
• Guided
• Or frustrating and confusing

This can help you identify systemic problems in your products or services and can also reduce churn by simplifying renewal paths.

6. After resolving a bug or technical issue

If your engineering or product team deploys a fix, CES helps verify whether:

• The issue is truly resolved
• The customer’s workflow is back on track
• Additional friction remains that wasn’t addressed

How to measure customer effort score?

Measuring score is straightforward, but getting reliable insights depends on when you ask the question, how you frame it, and how you calculate the customer effort score. 

Here is a simple, structured breakdown of the process.

1. Ask the right CES survey question

Most customer effort score surveys focus on a single core question that measures how easy or difficult it was for customers to complete a specific task or resolve an issue. 

The question is typically phrased as: 

“How easy was it to resolve your issue today?”

This question captures perceived effort immediately after the customer completes a particular action.

I rely the most on on-site surveys because they capture feedback in real time. When users encounter a problem while browsing, they can share their thoughts immediately instead of trying to recall the experience later. This makes it easier to identify friction at the exact moment it occurs, and compared to many other research methods, it’s also relatively cost-effective.

2. Choose your customer effort score scale

Brands commonly use one of the following customer effort score scales:

• 1-5 scale (1 = very difficult, 5 = very easy)
• 1-7 scale for more variance
• Likert-style agreement scale, from strongly disagree to strongly agree
• Emoji scale (simple and visual, often used in mobile flows)

Choose a scale that your users find intuitive and maintain consistency across touchpoints.

3. Trigger the CES survey at the right moment

Send the survey right after the customer completes a task or interaction, such as:

• Ended a support chat
• Made a purchase
• Completed onboarding, etc

The closer the survey is to the experience, the more accurate your CES will be

4. Collect both quantitative and qualitative feedback

A strong customer effort score survey includes:

• The rating question (quantitative)
• An optional open-text field to capture why they felt the experience was easy or hard (qualitative)

5. Calculate CES

The customer effort score formula is straightforward:

CES = (Sum of all customer effort ratings ÷ Total number of responses)

For instance, if 100 shoppers gave a total of 420 points, the CES score is 420 ÷ 100 = 4.2

This gives you an average customer effort score, which you can track over time or benchmark against industry norms.

What is a good customer effort score?

While there is no universal standard for customer effort score, anything above 5 on a 1-7 scale is considered good. This range represents a sweet spot where the customer’s problem is solved with minimal effort.

Customer effort score benchmarks:

• 1 to 7 scale: A score of 5 is good, and 6 or higher is excellent.
• 1 to 5 scale: A score of 3 or higher is generally considered good.

How to improve customer effort score?

High effort usually comes from broken workflows, unclear communication, repetitive steps, or slow support. 

Here are the most effective ways to improve your customer effort score.

1. Map and remove friction from critical journeys

Use behavior analytics, session recordings, heatmaps, and CES survey responses to pinpoint the exact moments where users struggle.

2. Streamline product or website flows

Customers often experience high effort because the journey is too long or confusing. Simplifying navigation, reducing unnecessary steps, and clarifying next actions make it easier for users to complete tasks quickly and effortlessly.

3. Strengthen your self-service experience

Make sure to develop a knowledge base with clearer, searchable articles or add FAQs for high-volume questions. When customers solve issues on their own, CES naturally increases.

4. Make your support interactions effortless

Even the best products require support, but the experience shouldn’t feel like work. Ensure customers can quickly reach the right support channel, avoid repeating information, and receive clear, actionable responses in minimal steps.

5. Test and iterate on improvements

Once you identify friction, run experiments to validate fixes.
