I quite like the simplicity and ease of use of FitBit’s survey (hosted by Getfeedback).
This question alone gives you invaluable insights into what benefits to offer members of the community and what attracts the majority of visitors. I’d estimate around 90% of communities are relying upon assumptions here rather than guesswork.
Better than the NPS score, is the answer to this question. This suggests whether people got the outcome they wanted from the community or not.
This data lets Fitbit drill deeper into whether specific groups of customers have a better or worse experience than others.
Like the above, this enables Fitbit to see if newcomers, veterans, or intermediate-level members are having better experiences with the community and they can adjust their efforts accordingly.
If you’re looking for a dead-simple survey that gives useful insight, this is a good place to start.
