The Keynote Mobile Commerce Performance Index - US shows the average response times, success rates and download speeds for downloading the homepage of selected sites of retailers on popular smartphones using Mobile Web Perspective over Air. The retail sites that appear in the Index were selected to provide an industry benchmark for well-known company sites.
Note: Keynote has recently updated its Mobile Web Perspective over Air measurement technology to support 4G connection speed. Average Response Time measurements prior to this change reflect the user experience at up to 3G connections, only.

Measurements are taken at highest possible network speeds supported by carrier at the time of the tests. Network conditions can fluctuate and network speeds are subject to these variations. Since variability reflects real end-user experience, measurements captured at all speeds are factored into the evaluation of over the air (OTA) performance, availability and download rates.
