More than half of US consumers use smartphones to research and purchase products and services. To keep up with shifting customer behavior, retailers’ mobile site search and browsability functionality must stay competitive. To see how retailers meet and deliver against consumer expectations, Forrester evaluated the websites of 10 US retailers in the Digital Experience Review™ of retail mobile sites. This report analyzes how leading retailers’ mobile site search and browsability experiences help their customers find what they want — and fast. It is the first report in a series that provides digital leaders with best-practice examples of leading retail mobile site features.
