One of the most exciting things about Net Promoter is that in building your NPS, you create a tremendous asset. Promoters will not only buy from you, and keep buying for you--they are are also far more likely to:

- refer business to you

- take reference calls and site visits

- provide testimonials (check out these impressive video testimonials from Intel's website.)

- participate on yoru social media sites

- say great things about you on other social media sites

- speak about you at industry events

- engage in customer co-design

- participate in advisory boards

- participate in marketing and advertising and initiatives

In other words, you have a community of highly credible sources that can help improve your sales, marketing and branding efforts in measurable ways.

I think the next great question for NPS is, "How do we organize our promoters into customer reference programs, advisory boards, online and in-person customer communities, executive forums, and other customer engagement efforts to create even more mutual value for them and for our firm?"
