Net Promoter Score as a Brand Strength Metric

Why one question predicts brand growth

Frederick Reichheld, the founder of the methodology at Bain & Company, tested dozens of question formulations and left only one working version: 'How likely is it that you would recommend us to a friend or colleague?' Any softened variants — for example, 'if a friend asked' — distort the picture and increase the number of positive ratings threefold. People answer more honestly when they imagine a real situation, not a hypothetical one.

The connection with brand strength is direct. A promoter is not just satisfied — he is willing to spend social capital on your recommendation. According to Bain & Company calculations, a customer retention growth of just 5% increases profit by more than 25%: loyal customers buy more over time, reduce operational costs for acquisition, and bring new buyers for free. A brand with a high NPS grows not because of increased advertising budget, but because part of new customers come from word-of-mouth — the cheapest and most persuasive sales channel.

Transactional and Relational NPS: Two Different Questions

Confusing these two types of survey is a common mistake that leads companies to misinterpret the numbers. Transactional NPS asks about a specific experience: after a purchase, delivery, or support call. Relational NPS asks about the overall relationship with the brand, outside the context of the last transaction.

Both types should be used, but not instead of each other. Transactional NPS catches operational issues precisely — for example, if the indicator dropped sharply after changing the courier service. Relational shows whether the brand is growing as an asset over the long term, regardless of occasional failures.

Case: how a call within an hour turns a critic into a promoter

A network of online subscription services received a rating of 3 from a client who wrote in the open field: "Charged money after canceling the subscription, support has not responded for three days." The standard scenario — to record the rating in a report and forget. The company acted differently: the alert system automatically passed the inquiry to a manager, who called the client within 40 minutes.

The manager apologized, refunded the money the same day, and explained why the billing failure occurred. A follow-up survey a month later showed a rating of 9 — the client not only stayed, but became a recommender to colleagues, specifically mentioning the speed of response to the problem. This is the essence of Closing the Loop: it's not the error itself that shapes brand perception, but how quickly and humanely it is responded to. One hour — a critical window: after a day, disappointment solidifies, and regaining loyalty becomes many times more expensive.

What to do with critics and neutrals in practice

Monitoring NPS without action — a waste of resources. Each category requires its own action plan, and they should not be mixed.

• Critics (0-6) — a priority for immediate contact. The goal is not to justify, but to solve the problem and confirm that it has been eliminated systematically, not just temporarily.
• Neutrals (7-8) — the most underestimated group. They don't complain, but won't recommend either. Work with them involves a targeted question: what was missing to reach the maximum rating, and targeted elimination of that barrier.
• Promoters (9-10) — a source of growth if not ignored. It's precisely with them that you should ask for permission to publish a review, case, or participate in a referral program.

The mistake of most companies — focusing only on putting out fires with critics, forgetting that turning neutrals into promoters yields a greater NPS increase in scale than saving individual dissatisfied customers.

Why the question 'Why?' is more important than the number itself

NPS score without an open-ended comment is like a diagnosis without anamnesis. Without an answer to 'why did you give this rating', the metric loses up to 80% of its practical value: you know the customer is dissatisfied, but you don't know exactly why — whether it's price, speed, product quality, or communication with support.

Promoters in open-ended responses reveal the brand's real competitive advantages — often those that marketing itself hasn't formulated so precisely. Detractors show pain points without embellishment. The problem is that manually collecting these responses and analyzing them through Excel is a bad idea: texts need to be automatically categorized by themes (delivery, price, service, product) and passed on to relevant departments for action, otherwise insights will simply get lost in reports.

NPS doesn't work alone: CSAT, CES, and industry benchmarks

NPS answers the question 'would you recommend', but doesn't explain whether a specific interaction was easy or painful. For that, CSAT (satisfaction with a specific experience) and CES (Customer Effort Score — how much effort it took the customer to solve the task) are needed. The combination of these three metrics provides a complete picture: CES captures operational friction, CSAT evaluates a single contact, and NPS shows the accumulated effect on brand reputation.

Comparing your NPS to an abstract 'good indicator' is another common mistake. According to SurveyMonkey data from a sample of more than 150 000 organizations, the average NPS is 32, and among the top 25% companies, it is 72 and above. However, the variation by industry is enormous:

The difference between 71% in insurance and 4% in online applications doesn't mean the latter industry performs worse. It reflects market specificity: applications are used by large numbers and usually for a short time, competition is huge, and the switching cost to an alternative is minimal. For such an industry, strategy is not built on chasing the number from insurance, but on retention through constant product improvement and managing churn, not classic word-of-mouth marketing.
