There was not much movement among the retailers in the Keynote Mobile Commerce Performance Index last week. The biggest change came from Sunglass Hut, which increased its standing by four positions, cracking the week’s top five mobile performers.
Sunglass Hut achieved a score of 753 out of 1,000, its m-commerce site home page loading on average in 4.38 seconds and doing so successfully 98.48% of the time. It came in fifth out of the 15 retailers in the weekly index from mobile and web performance management firm Keynote Systems Inc. provided exclusively to Internet Retailer.
StrandBooks.com again came in first with a score of 813, its mobile home page loading in a quick 2.4 seconds with a success rate of 97.52%. Barnes & Noble moved up one spot to come in second with a score of 800, its m-commerce site home page loading in 4.18 seconds with a success rate of 98.76%.
Walmart.com dropped one spot to third with a score of 789, its mobile home page loading on average in 3.53 seconds and doing so successfully 98.17% of the time. And Dell stayed in fourth with a score of 783, its mobile home page loading in 4.57 seconds with a success rate of 98.90%.
The index average score for the week was 663, down 10 points. The average load time was 5.18 seconds with a success rate of 98.26%. Click here and select Keynote Mobile Commerce Performance Index to see complete results for all of the index’s 15 merchants for the week ending Nov. 26.
“Last week’s mobile data should be especially interesting because it would indicate if any mobile site was not prepared for the expected increase in user visits,” says Herman Ng, mobile performance evangelist at Keynote Systems. “Overall, all sites on the index performed quite well. Except for one site, all the sites had a weekly average success rate above 97%. Load time and overall ranking were mostly consistent with the previous week’s metrics. On closer examination of the data it appears that two mobile sites experienced performance spikes on Thanksgiving Day and another two sites experienced lower than normal success rates, also known as reliability; however, they all recovered on Black Friday and the rest of the holiday weekend. While it’s ‘so far, so good,’ any out of the ordinary performance pattern should not be ignored, as it could be an early warning sign of larger issues.”
Keynote Systems measures the 15 representative m-commerce sites for Internet Retailer. The sites include merchants in various categories and channels, and of various sizes, ranging from such giants as Sears and Foot Locker Inc. to midsized retailers like Sunglass Hut and K&L Wine Merchants.
Keynote repeatedly tests the sites in the index Monday through Friday from 8 a.m. through midnight Eastern time, emulating three different smartphones on three different wireless networks: the iPhone on AT&T, the BlackBerry Curve on Sprint and the Droid (which uses the Android operating system) on Verizon. Keynote combines a site’s load time and success rate, equally weighted, into a single score. Given 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’s average score is the midpoint among all the sites’ scores.
