SSI Measures & Calculates Net Promoter Score®

--NPS Provides Proactive Measurement of Customer Loyalty and Endorsement --

SHELTON, Conn., Oct. 24, 2017-- SSI can now measure and calculate Net Promoter Score®, enabling companies to survey 17 million panelists in order to measure customer loyalty and gather insights to improve long-term customer relationships. Net Promoter Score, used by companies since its introduction in 2003, measures the loyalty that exists between a brand and its customer base. 

“NPS has been the gold standard for companies looking to assess brand loyalty,” said Andy Jolls, SSI’s chief marketing officer.  “While these same companies have done a good job of tracking their own Net Promoter Scores over time, many aren’t tracking the score movement of their competition.

“There are other advantages of running NPS with SSI panelists such as correcting for response bias,” added Jolls.  “Because brands can bias research by asking questions directly, there is a value proposition for having a third party administer the questionnaires.  A study of a brand’s customers based on respondents in their own database could produce different scores than those same brand’s customers from the SSI panel due to numerous factors.  SSI can provide a whole new view on NPS.”

NPS methodology typically asks a singular question: Would you recommend this product or service to someone else?  Respondents can answer on a scale of 0 to 10, with 0 being “not at all likely” and 10 being “extremely likely.”  The resulting score ranges from negative 100 to positive 100 and is calculated by subtracting the percentage of detractors from the percentage of promoters.  NPS proactively benchmarks the loyalty of a company’s customers over time, and the system is used globally as a key performance indicator in companies of all sizes.
