In my last blog, I explained exactly what drives NPS scores. So now I’m going to reveal how you turn insight into action.
Firstly, let’s consider pick up with investigating a decline NPS. In this situation, it's natural to focus on detractors, but don't overlook your promoters.
The positive NPS drivers highlight the themes most commonly associated with customers who are highly likely to recommend your business.
It's also worth considering whether the reasons customers recommend you have changed over time. If customers stop mentioning strengths that once differentiated your business, or begin adding small caveats to otherwise positive comments, this may indicate changing expectations or emerging areas of friction before they become larger issues.
Protecting these strengths is just as important as addressing areas for improvement.
Meanwhile, negative NPS drivers identify the recurring themes associated with detractors, helping you spot patterns across customer feedback rather than isolated comments.
For example, if communication delays, lengthy processing times or unclear information repeatedly appear in detractor comments, they're likely to have a greater impact on NPS than one-off experiences.
Understanding these recurring drivers helps you prioritise improvements that will have the greatest impact.
What are customers actually saying?
Sometimes the most valuable insights come directly from your customers' own words, which you can find at your dashboard.
The “negative sentiment comments by theme chart” helps you understand why customers feel that way, allowing you to identify pain points for a specific date range or over time.
By grouping negative comments into themes such as communication, customer service or the process, you can quickly identify recurring pain points and understand the context behind a decline in NPS.
Review volume
Lastly you need to determine the length of the decline. Has it been a few months or just this last month?
Low review volumes can make NPS volatile. A single response may shift the score significantly, so trends over time are more reliable than individual monthly scores.
What should you investigate first when NPS declines?
If you notice your NPS falling, consider working through the following questions:
• Has the decline happened gradually or suddenly?
• Which themes have become more negative?
• Are the same issues appearing repeatedly across customer comments?
• Is one product driving the decline?
• Have the reasons customers recommend your business changed?
Turning insight into action
A declining NPS rarely has a single cause. More often, it reflects changing customer expectations, recurring friction points or shifts in how customers perceive their experience.
That's why the score should be viewed as the starting point of your investigation, not the conclusion.
By combining NPS with themes, sentiment analysis and customer comments, you can move beyond asking, "Why has our score changed?" to answering, "What should we improve next?"
