We recommend asking so that the respondent understands the question the same way as the asker
We recommend using, for example, “yes” – “no“, multiple-choice answers (single or multiple selection), a 1-5 scale and free-text solutions.
We recommend avoiding asking for feedback on the 11-point scale of the NPS or recommendation index (Net Promoter Score), because it excludes those who give a 7 or 8 from the positive ratings. We find it too general, too extreme and, for many respondents, hard to understand. A recommendation question also gives no concrete information about what is liked or disliked. Technically, though, our platform calculates the NPS formula nicely ((9+10) – (0-6)), and if clients wish, we do use this question too (in that case, however, we do not mix it with other questions whose result formulas differ from that of the recommendation index).
