Understand the drivers behind NPS & CSAT

The NPS score is 7 – but why? Numbers alone aren't enough. Understand why customers are promoters or detractors, which topics drive your scores – and derive concrete actions to sustainably improve NPS and CSAT.

The Challenge

NPS 32. But why? The number alone won't get you far.

Your NPS score has dropped – but the number alone doesn't tell you where the problem lies. Was it support? Delivery time? The product itself? Without systematic analysis of the comments, you're in the dark and risk pulling the wrong levers. Yet every comment contains a concrete hint – if you analyze it systematically.

Example

Top 5 reasons for low NPS scores – automatically identified

A telecommunications company analyzed 5,000 NPS comments with deepsight. The automatic driver analysis showed: 'Support wait time' was the most frequent detractor reason (28%), followed by 'unclear billing' (19%) and 'network coverage' (15%). For promoters, 'fast problem resolution' (34%) and 'friendly service' (22%) dominated. The CX team could immediately focus on the two most impactful levers.

Detractors vs. Promoters: What are they really saying?

deepsight automatically separates NPS comments by score groups and shows which topics differ between Detractors (0-6), Passives (7-8), and Promoters (9-10). This way you identify not just what's going wrong – but also what creates excitement. The key: From comment to concrete action.
