The Keynote Mobile Retail Index - World Edition shows the average response times, success rates and a composite score for downloading the homepage of selected sites of retailers using Mobile Web Perspective over Air. Keynote repeatedly tests the sites in the index hourly and around the clock over two Tier 1 wireless networks in each country (Australia, France, Germany, Japan, Sweden, UK and US) over popular smartphones. The retail sites that appear in the Index were selected to provide an industry benchmark for well-known company sites.
Sites from this list may be temporarily removed from weekly published results due to insufficient data points for a particular week.
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.
