Amazon’s m-commerce site ranked first in overall mobile testing by Gomez.
Amazon.com finished with the best composite score among large web retailers for mobile performance in December, says Compuware Gomez. Gomez tests 15 large retailers every month for mobile response time, availability and consistency on four mobile devices, each on a different wireless carrier: Apple’s iPhone on AT&T, Sprint’s HTC Hero, T-Mobile’s HTC Dream and Verizon’s Droid.
In December, Amazon.com produced an average mobile response time of 2.99 seconds, an availability score of 99.23% and an average consistency score of 3.28 seconds, giving the retailer the best average across all four mobile devices for all three measurements.
The mobile sites for L.L. Bean and Sears came next in the December mobile rankings. LLBean.com posted an average response time of 4.17 seconds, an availability score of 98.72% and an average consistency score of 3.14 while Sears.com posted an average response time of 3.47 seconds, an availability score of 98.84% and an average consistency score of 3.56. Newegg.com and VictoriasSecret.com rounded out the top five retailers in the study.
