What is Customer Effort Score (CES)?

Understanding Customer Effort Score

Customer Effort Score (CES) measures how much effort a customer has to expend to get an issue resolved, a request fulfilled, or a task completed. Introduced by the Corporate Executive Board (now Gartner) in 2010, CES has become a powerful predictor of customer loyalty.

The premise is simple: customers value ease. When interactions with your company are effortless, customers are more likely to remain loyal. When they're difficult, customers are more likely to churn and share negative experiences.

The Key Insight

Research published in the Harvard Business Review found that reducing customer effort is a better predictor of loyalty than customer delight. The study revealed that 94% of customers who had low-effort experiences intended to repurchase, compared to only 4% of those who experienced high effort.

The CES Question

CES surveys ask customers to rate the ease of their experience:

"To what extent do you agree: [Company] made it easy for me to handle my issue."

Or alternatively:

"How easy was it to get your issue resolved today?"

The CES Scale

CES typically uses a 7-point scale from "Strongly Disagree" (high effort) to "Strongly Agree" (low effort):

How CES is Calculated

Unlike NPS or CSAT, CES is calculated as a simple average of all responses. This gives you a score on the same scale as your survey (1-7 in most cases).

The CES Formula

Interpreting Your CES Score

On a 7-point scale, here's how to interpret your CES:

CES Range	Rating	What It Means
6.0 - 7.0	Excellent	Effortless experiences. Customers find interactions easy.
5.0 - 5.9	Good	Low effort overall with minor friction points.
4.0 - 4.9	Average	Moderate effort required. Room for improvement.
Below 4.0	Needs Work	High effort required. Significant friction exists.

CES vs. NPS vs. CSAT

Each metric provides unique insights. Here's how they compare:

Metric	Measures	Best For	Time Frame
CES	Ease of interaction	Service interactions, support, processes	Immediate, transactional
CSAT	Satisfaction with experience	Specific touchpoints, transactions	Immediate, transactional
NPS	Loyalty & advocacy	Overall relationship health	Long-term, relationship

Many companies use all three metrics strategically: CES for service interactions, CSAT for specific touchpoints, and NPS for overall relationship tracking.

CES Use Cases and Examples

1. Customer Support Interactions

The most common use case for CES. Measure effort after support tickets, live chat, or phone calls.

2. Self-Service Experiences

Measure the effort required to use help centers, FAQs, or knowledge bases.

3. Onboarding Process

Track effort during product setup and activation to identify friction points.

4. Purchase & Checkout

Measure checkout friction, return processes, or account management tasks.

Strategies to Reduce Customer Effort

Once you identify high-effort areas, here's how to address them:

1. Enable First Contact Resolution

Train and empower your support team to resolve issues in a single interaction. Every additional contact multiplies effort.

2. Minimize Channel Switching

Don't force customers to switch from chat to email to phone. Whatever channel they start with should be able to resolve their issue.

3. Anticipate Next Issues

Train agents to address related issues proactively. If a customer asks about billing, check if their payment method is expiring soon.

4. Improve Self-Service

Invest in searchable knowledge bases, intuitive FAQs, and chatbots that actually help. Many customers prefer self-service when it works well.

5. Use Simple Language

Avoid jargon in your communications. Clear, simple language reduces cognitive effort and confusion.

6. Streamline Processes

Audit your customer-facing processes for unnecessary steps. Every additional field, click, or page adds effort.

Best Practices for CES Surveys

1. Survey immediately: Send CES surveys right after the interaction while the experience is fresh. Timing is critical.
2. Focus on specific interactions: CES works best for evaluating discrete touchpoints, not general satisfaction.
3. Add an open-ended follow-up: Ask "What could we have done to make this easier?" to get actionable insights.
4. Segment your data: Break down CES by channel, issue type, agent, or customer segment to find specific problems.
5. Act on low scores quickly: High-effort experiences create churn risk. Reach out to customers who report high effort.
6. Track trends over time: A single CES score is a snapshot. Track changes to see if your improvements work.

Industry CES Benchmarks

CES benchmarks are less standardized than NPS or CSAT, but here are general guidelines on a 1-7 scale:

• Technology/SaaS: 5.0 - 5.5
• E-commerce: 5.5 - 6.0
• Financial Services: 4.5 - 5.5
• Telecommunications: 4.0 - 5.0
• Utilities: 4.5 - 5.0
• Healthcare: 5.0 - 5.5

The goal is continuous improvement of your own score over time, not just meeting benchmarks.
