Performance Index: Mobile Commerce (Retail) – US
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.

- "Response Time" is the average time in seconds it took to download the website to the mobile phone
- "Success Rate" is the percentage of time the website successfully downloaded the complete content to the mobile phone
- A combined score is created (equally weighting their response and reliability). The higher the score, the more high quality the site is technically. The distance between sites (in terms of their response and reliability) is represented by the distance between scores
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.
