Basically, NPS is a measure of how many of your customers like your brand enough to recommend (or promote) it to others. If more people recommend you than not, you’re score is positive and generally doing well. If an equal amount promote as do not, you’ve got some work to do to push that needle from neutral into the plus column. If more people don’t promote your business than do, you need to find out why. Referrals, after all, are the best form of advertising any enterprise can have. Create an NPS survey to see where you rank.
