Clusters | Ratings |
Promoters | 9 – 10 |
Passives | 7 – 8 |
Detractors | 0 – 6 |
Then, use this formula to measure your NPS, which will give you a score between -100 and 100:
NPS = % of Promoters – % of Detractors
For example, if 10 percent of your customers are ‘Detractors’ and 40 percent are ‘Promoters’, you have a Net Promoter Score of 30. Having a positive NPS means that you have more Promoters than you do Detractors. As such, the higher your NPS, the better.
Why you should measure Net Promoter Score
There are many benefits to measuring NPS, especially when collected and leveraged as a high-level CX metric:
1. It’s an easy to question to ask and to communicate internally
Since it uses a single straightforward question and scale, companies can easily measure NPS using any medium through which you communicate with your customers, whether it’s by phone, e-mail or Web, and communicate findings internally to key stakeholders.
2. You should always monitor your company’s “recommendability”
As individuals, we’re always curious about what people say about us to other people. A company is no different, especially since customer loyalty can have a significant impact on the bottom line. NPS provides a way for you to measure the impact of your website experience on your visitors’ likelihood to recommend you to their peers.
3. Likelihood to recommend can only be measured with customer feedback
Once visitors leave your website, you can’t track what they’ll do next. The only way to truly know the likelihood that your visitors will recommend you after their visit, or dissuade other people from trying your offerings, is by collecting customer feedback.
4. It has become a mainstream metric to measure
Since its introduction, NPS has been adopted by thousands of companies in different industries, and the number keeps growing. Simply put, it’s likely that your executives and managers are now expecting to be updated on the company’s NPS on a regular basis.
5. It provides a springboard to understand what drives your customers to recommend you
Similar to other key CX metrics like Customer Satisfaction and Task Completion, NPS is a metric that can encompass a visitor’s entire website experience, and can be influenced by several factors. By first identifying your Promoters and Detractors, you can then dig deeper into their feedback, or even cross-reference their feedback with web analytics or session replay, to better determine the aspects of their experiences that drove them to become a Promoter or Detractor.
Criticisms of Net Promoter Score
Before looking at a use case showing how you can leverage NPS in your organization, it’s important to note that NPS is not without its critics. Some of the most widespread criticisms surrounding NPS include:
1. Its simplicity may be insufficient to gauge something as complex and long-term as customer loyalty
Bob Hayes, PhD, points out that customer loyalty is multidimensional, and can be comprised of a customer’s likelihood to do each of the following:
- Stick with the same provider / vendor (Retention Loyalty)
- Purchase more items from a company in the future (Purchasing Loyalty)
- Recommend to another person (Advocacy Loyalty)
Hayes argues that NPS only deals with the Advocacy dimension but doesn’t consider the other key dimensions of customer loyalty.
2. More of a relationship-level metric than transactional-level metric
Many companies use NPS to gauge how customers feel about a single interaction with the company (“transactional-level”). However, as explained by Bruce Temkin, founder of the Temkin Group, NPS is more ideal as a “relationship-level” metric, and finds that companies who use it as such see more success in driving positive change internally than those who use it at the transactional-level.
Use Case: The website attributes that drive website visitors to recommend
Knowing which of your visitors are Promoters, Passives and Detractors is great. Knowing what aspects of their website experience made them that way is even more valuable.
These insights can be found by asking your visitors to answer a survey that includes both the Net Promoter Score question and questions about specific aspects of your website.
For this use case, let’s look at a fictional ecommerce company that primarily sells large-ticket items, and have seen their Net Promoter Score take a tumble in recent months. To get to the bottom of this decrease, they first use text analytics to dig through their respondents’ unstructured feedback to see if any website attributes stand out. Based on their analysis, they modify their survey to ask their visitors to rate their satisfaction with specific attributes that touch on the website’s navigation, content and interactivity.
Here are the results of these attribute questions:
Based on today’s visit, how would you rate our website as one that:
Website Dimension |
Attribute Name |
Attribute Question |
Rating (Mean) |
Navigation | Ease of Use | is easy for you to navigate? | 6.7 |
Navigation | Discovery | enables you to find what you are looking for? | 6.4 |
Content | Clarity | presents the information clearly? | 6.7 |
Content | Multimedia | has enough visuals (photos & videos)? | 6.1 |
Interactivity | Self Service | provides you with the tools and features that enable you to help yourself? | 7.2 |
Interactivity | Contacts | enables you to identify and contact the right person? | 6.3 |
Compared to the other attributes examined, the company’s website performs well in terms of its “Self Service” aspects, while its multimedia content leaves something to be desired.
But which of these attributes actually had an impact on their visitors’ likelihood to recommend the website to a friend or colleague?
To answer this question, a multiple regression analysis is performed to measure the impact that each individual website attribute has on a visitor’s likelihood to recommend the website to their friends or colleagues. This analysis not only identifies the variables with a statistically significant impact on the visitor’s NPS score, but also how each website attribute compares in terms of its impact.
The multiple regression analysis finds the following attributes to have a statistically significant impact on NPS, which are categorized into quadrants to highlight where the company should focus its efforts:
A few insights that the ecommerce company can take from this chart:
Findings | Analysis |
“Discovery” and “Ease of Use” both had low ratings but had the highest impact on NPS. | Due to their high impact on NPS and underperforming ratings, the website’s navigation is among the main culprits for the decreasing NPS score. |
“Self Service” had both the highest rating and a large impact on NPS. | This is an ideal position for any website attribute to be. It is unlikely to be contributing to the company’s tumbling NPS. |
“Clarity” and “Contacts” both had low ratings, but comparatively low impact on NPS. | The company should monitor their visitors’ experience with these items, although improving these items could still be worthwhile. |
“Multimedia” did not have a statistically significant impact on NPS. | Despite having the lowest rating of all the website attributes examined, the ability to actually reach this content was more crucial for these visitors. |
Based on these findings, the ecommerce company can decide to dig further into the navigational aspects of their website, which includes modifying their research to collect more in-depth customer feedback and insights from their visitors regarding the website navigation.
This can then allow the company to better determine how to best streamline their website experience and boost the likelihood that their visitors will recommend the company and its website to their peers.
Final thoughts
Word-of-mouth can be your best or worst friend. In his book, Wind In Your Sails, entrepreneur David J. Greer points out that:
“A customer talking about their experience with you is worth ten times that which you write or say about yourself.”
By collecting the Net Promoter Score, you can gain a sense of your website’s impact on what Reichheld refers to in his article the Harvard Business Review as “the ultimate act of loyalty” – recommending your organization to their peers.
With its short-term and long-term implications to your organization’s bottom line, NPS can be a useful CX metric to measure across your organization using a Voice of the Customer (VoC) program.
