Why an NPS of 90 might be hiding fragility in your customer loyalty
Author: Elena Benitez, CEO & Founder of Gerundio.
There's an old tale in marketing directions that says a satisfied customer is a loyal customer. In results meetings, dashboards full of «green faces» and scores are celebrated. Net Promoter Score (NPS) enviable. However, many of those same companies watch with bewilderment as their metrics Churn (abandonment) increase while their satisfaction surveys shine.
In Gerundio, we have learned that Satisfaction is a mirage; loyalty is the reality. Satisfaction is merely the absence of friction, but it is not the engine of growth. For brands that require sustained bonds, loyalty is not a score; it is a relationship system that directly impacts long-term business decisions.
How to Correctly Measure CSAT & NPS (And Why It's Not Enough)
The fundamental error lies in not understanding what each indicator measures and where its usefulness ends:
- Customer Satisfaction Score It's a transactional reaction metric. It tells you if the coffee was hot or if the app opened quickly. It's useful for operations, but it has zero predictive power about the future of the relationship.
- Net Promoter Score It's a metric of intent. The problem is that intent isn't the same as behavior; there's a huge gap between saying you'd recommend something and actually buying it again when a competitor offers a 10% discount.
When we become obsessed with these metrics, we fall into the «Vanity engagement». A high score may simply be the result of a user who hasn't found a sufficient reason to complain, but also doesn't have a strong reason to stay.
From Mirage to Profitability: The Effort Factor (CES)
A Fintech can have an outstanding NPS because its interface is ‘pretty’, but if the effort to resolve a clarification or understand a fee is high, loyalty is fragile. In our study Decoding Financial Digitalization, we observe that digitalization is not an end in itself, but a means to build trust; if the technology does not reduce the user's cognitive effort, the relationship breaks down. Customer Effort Score The experience KPI that best predicts this behavior is: a customer who has to make little effort to gain real value is a customer who stays.
Loyalty as a relational phenomenon
To move from a reactive strategic capacity to a structured acquisition and profitable, we must stop seeing loyalty as a points program and start seeing it as an ecosystem.
Our methodology of Deciphering allows us to observe how these relationships are built—or broken—from real data. Instead of just measuring «happiness,» we focus strategic design on variables that move the business needle:
- Customer Lifetime Value (LTV) The real value a customer brings throughout their history with the brand.
- Churn Prevention Identify friction before the user decides to leave.
- Customer Stickiness Design indispensable services that generate real and sustained adoption.
Three principles for redesigning your experience KPIs
- From Data to Sensemaking: No accumulate points. Use the UX Research to understand the «why» behind the number. Data tells you what's happening; strategic design tells you what to do.
- Design for emotional loyalty, not just transactional: Cashback programs are replicable. Real loyalty is built through empathy and understanding human needs. Create Loyalty Loops where experience is the value.
- Link CX to Business Outcomes: Every satisfaction metric must be connected to a business metric. If CSAT goes up but purchase frequency goes down, your relationship system is broken.
