Net Promoter Score Is a Comfort Metric, Not a Growth Strategy
CMSWire contributor argues that Net Promoter Score (NPS), despite its widespread adoption, is a lagging indicator that fails to predict revenue growth. Citing independent research including a 2023 Marketing Science Institute study of 30+ US companies, the article finds NPS explains only about 1% of variance in share of wallet and 0.4% of changes in customer spend. The author advocates for behavioral metrics like repeat purchase, retention, and share of wallet over survey-based stated intent, calling NPS a comfort metric that fosters metric displacement and Goodhart's Law issues. While acknowledging NPS may serve as a directional signal in some contexts, the author argues it should not be treated as a decisive growth engine. Part 2 will include responses from Qualtrics and Rokt.
Article challenges the predictive validity of NPS, a widely used CX metric, citing independent research; relevant to MarTech and measurement practices, but not an industry-shifting event.

CX Gap Persists After 20 Years Despite Billions Invested
Despite decades of investment in customer experience (CX) programs, a persistent disconnect remains between how companies perceive their CX and how customers actually experience it. Bain & Company's 2005 study found 80% of executives believed they delivered superior CX, while only 8% of customers agreed. Subsequent research by Capgemini (2017) and SAP (2026) shows similar gaps. The article argues that this 'delivery gap' is not a technology problem, but an accountability and culture issue. Root causes include measuring what's easy to report rather than actual experience, decorative feedback loops, and employee experience being deprioritized. As AI-driven CX investment surges, the author warns that automation without cultural and accountability fixes will merely scale the existing disconnect.
Retailers can boost holiday checkout joy with relevant offers
This sponsored article by Rokt discusses how retailers can enhance the holiday checkout experience by presenting relevant partner offers and rewards invitations after purchase confirmation. It emphasizes timing, restraint, and relevance, suggesting that offers should not relate directly to purchased items but rather to customer interests. Retailers are advised to measure value beyond conversion, including customer feedback and repeat purchasing, while advertisers should focus on incremental customer acquisition. The article cites Deloitte's forecast of U.S. holiday ecommerce sales of $316.1–$318.9 billion for November 2026–January 2027.
