What is Customer Effort Score (CES)?

Customer Effort Score (CES) is a type of customer satisfaction survey used to induce customer loyalty by reducing customer efforts by measuring the ease of service experience with an organization. It asks customers to rate the ease of using products or services on a scale of “very difficult” or “very easy”.

Customer Effort Score was originated by the Corporate Executive Board using a simple, cross-sectional research approach without the benefit of actual measures of customer behavior in the research model. An extended review of their findings can be found in their book, The Effortless Experience. The research focused on factors affecting customer attitudes in a customer service environment, particularly the one with some problem that needed to be addressed. The level of effort the customer had to expend proved to be the key factor determining a customer’s likely future purchasing and word-of-mouth behaviors, as measured by the survey.

The researchers do state that high customer effort is an indicator of the higher probability of customer disloyalty, but that low effort is not likely to drive positive loyalty behaviors. Simply put, service requiring a significant amount of work by the customer may lose the customer, but low effort does not assuredly indicate that the customer will make a purchase again. Customer Effort Score is really a customer feedback metric that measures ease of interaction instead of satisfaction rate.

Example of Customer Effort Score

The attention that CES is gaining these days is tremendous and the need to understand customers better is also on a rise. Here is an example showing how exactly CES works and what kind of questions are to be asked to understand whether the customer is satisfied or not.

Application of Customer Effort Score

After evaluating feedbacks received for a Customer Effort Score survey, if your organization has a high average, it is indicative of the fact that your company is making things convenient for the customers while a low average is indicative of the fact that there’s a lot of room for improvement of customer satisfaction. An organization that has constant hindrances in keeping their customers satisfied in terms of service should use Customer Effort Score and it is applicable to all the process across the organization.

Due to this, you can plan actions that would mend your services. The Kano Model from Japanese quality guru presents exactly this relationship. Some expected deliverables, like low customer effort, drive satisfaction while other factors drive delight and loyalty.

Customer Effort Score is one of the survey types implemented after every customer transaction with an organization. Thus, its actual use is transactional following some customer interaction. Further, the nature of CES survey is geared towards problem handling in a self-service environment.

Advantages and Disadvantages of Customer Effort Score (CES)


  • It’s better at predicting brand loyalty and repurchases and this makes it less volatile than the other scoring models.
  • This scoring model is applicable to all client processes which makes it extremely easy to make corrective actions can be taken at respective client process levels.
  • Due to these factors, it’s highly reliable to conclude customer behavior and satisfaction.


  • This scoring model is limited to service in particular and not your overall business.
  • It only gives results of whether customers find it difficult to use a service or not, why are they facing the difficulty or what are those difficulties in the first place remains unanswered.
  • The impact of factors like your cost, competitors or product quality is not taken into consideration.

Customer Effort Score vs Net Promoter Score

Customer Effort Score (CES) and Net Promoter Score (NPS) are correlative surveys with their own set of advantages and disadvantages. Both Customer Effort Score and Net Promoter Score calculate customer loyalty and satisfaction but there are certain situations where NPS is more effective than CES and there are some other situations where the other way round holds true. They both ask different sets of questions that are more or less complementary to one another.

NPS depicts the likelihood of recommendation – “How likely are you to recommend Company X to a friend or colleague?”. It is usually used to analyze brand shareability and loyalty but fails to evaluate customer behavior with respect to their latest interaction with the organization. This is where Customer Effort Score comes in.  

Customer Effort Score shows how loyal the customer can be as it asks them to rate the difficulty they faced with the organization’s services, lower the difficulty, better it will be for brand loyalty. High difficulty levels indicate that you need to make changes in the way you operate and make customer satisfaction your priority.

NPS is popular because of the degree of simplicity it offers to analyze two major aspects of business – customer loyalty and anticipated business evolution in the future. Promoters tend to stay committed to an organization and are also great sources of increase in business due to the recommendation. A promoter can be loyal to the organization but it does not mean they will stay loyal to the organization forever.

NPS is an overall customer interaction measurement parameter and cannot be used while focusing on improving customer service. Whereas, CES measures ease of solving customer issues and can be extremely effective in understanding obstacles in customer services in order to eliminate them and indirectly increase customer loyalty.

Customer Effort Score vs Net Promoter Score

Customer Effort Score Benchmark

All successful companies are constantly benchmarking their competition. They have to know what they have to match up with day-in and day-out if their company is going to be successful.
-James Dunn

According to research done by CEB Global, the overall benchmarks of CES 2.0 is below:

If your CES percentage is under 70%, you may want to focus on pinpointing and removing obstacles that your customers are facing.

Using Competitive Landscape as Your Benchmark

“Competition is always a good thing. It forces us to do our best. A monopoly renders people complacent and satisfied with mediocrity.” Nancy Pearcey

Going by this quote and popular belief, the more relevant method to measure your score is by using your competitor’s score as a benchmark. This is a better method to measure your NPS or metric because this takes your industry into consideration.

Airlines, for example, bring more delight to customers than banks, thus they tend to have a higher NPS. Because of that nature, it would not be helpful to compare a department store to an insurance company.

Customer Effort Score vs Net Promoter Score Example

It’s found that the Airline industry has a typical NPS range between -4 to +57. United Airlines has an NPS of 10, ranks as one of the worst companies in the Airlines space. On the other hand, Verizon, for example, has an NPS of 7 which is considered one of the best in the industry.

Global Standards vs. Competitor Benchmarking

You certainly can compare your metric across global standards, but it is critical to note that scores will vary across geographic markets. If you have ever compared NPS in the US and Europe, you probably know the cultural and demographic differences when rating a company’s performance.

For example, European customers are more conservative with rating a company’s performance, making them less likely to rate you a 9 or 10. In other regions, you may find customers using the lower end and higher end of the scale, but skipping in between. Because of these differences, the absolute Net Promoter scores in one industry can vary dramatically. This is another reason why a good Net Promoter Score is subjective.

Comparing Your Metric Against Your Own

Since your metric is nothing but a vanity number on its own, it is impossible to give you a single number that represents a good Net Promoter Score, especially when you are starting out. The best way to find out if your number is “good”, is the one that’s better than your own scores in the past — your most important benchmark.

The best way to start measuring progress would be to compare your NPS against your score over the last quarter or six months. If you are noticing an increase of at least 10%, you are heading in the right direction and progressing toward building a successful business driven by organic growth. On the other hand, if you notice a significant decrease in NPS, this indicates that there is something wrong and you must quickly identify to discover the cause and take appropriate measures.

Instead of asking “What is a good score?”, focus first on understanding the drivers of the metric and how to improve it on a daily to produce long-term customer satisfaction. Remember, a good Net Promoter Score by itself is not a quantifiable metric to grow, rather your main goal should always be to listen, analyze, and act on your customer feedback.
