Customer satisfaction with e-commerce websites stages a comeback a year after suffering its first decline since 2004, according to the American Customer Satisfaction Index (ACSI). The e-commerce sector gains 1.8% to 81.4 on ACSI’s 100-point scale, nearly matching its all-time high of 81.6 set in 2007. The annual ACSI e-commerce report measures customer satisfaction with online retail, online brokerage, and online travel companies.
