Its m-commerce site home page loaded on average in 3.60 seconds and it did so completely and successfully 99.89% of the time. The weighted and combined figures for load time and success rate earned Buy.com an index score of 964 out of 1,000, reports mobile and web performance management firm Keynote Systems Inc.
Page load time is key in m-commerce, as mobile shoppers typically are on the go and crave speed. While Buy.com’s score earned it the top spot on the index, fifth place finisher Toolfetch.com LLC had the fastest page load time on the index at 2.70 seconds. A lower success rate of 99.47% dragged the tool retailer’s score down to 891.

Keynote Systems measures 30 representative m-commerce sites exclusively for Internet Retailer. The sites include merchants in multiple categories and channels, and of multiple sizes, ranging from such giants as Amazon.com Inc. to midsized retailers like Toolfetch.com LLC. Keynote tests the sites in the index every hour Monday through Sunday from 8 a.m. through midnight Eastern time, emulating three different smartphones on three different wireless networks: Apple Inc.’s iPhone 4 on AT&T, the HTC Evo on Sprint and the Droid X on Verizon. The HTC Evo and the Droid X run Google Inc.’s Android operating system. Keynote runs the tests in New York and San Francisco.
Keynote combines a site’s load time and success rate, equally weighted, into a single score. Given that both performance and availability are important, the score reflects the overall quality of the home page; a higher score indicates better performance. Scores also reflect how close sites are to each other in overall quality. The index average score is the midpoint among all the sites’ scores.
