The retailer bounces back up a mobile site performance index after a week of errors.
Over the course of the last three weeks on the Keynote Mobile Commerce Performance Index, Newegg Inc. went from No. 12 out of the 30 sites measured to No. 20 to this week’s No. 9. What happened? A cacophony of page loading errors that diminished the retailer’s mobile commerce site success rate, the percentage of time a page loads completely and successfully, Keynote Systems Inc. says.
For the week ending Sept. 9, the m-commerce site home page of Newegg, No. 34 in the Internet Retailer Mobile Commerce Top 300, sometimes returned content errors to consumers requesting the page. These errors were caused by a cookie and a third-party server call, which could be for an image or other page object stored on a content delivery network, for example.
Newegg says it did not make any changes to the site that week as it is focusing now on redesigning the site for a launch soon. It did not elaborate on the errors.
“Third-party calls are usually ads, cookies, web metrics analysis tools or site content hosted by a content delivery network,” says Haroon Chohan, mobile and Web performance expert at Keynote Systems. “It’s important to understand how these third-party calls can impact the overall performance and availability of your site. If not monitored closely, third-party calls can cause significant performance and availability issues that can frustrate customers.”
The errors ceased during the week ending Sept. 16, when Newegg’s m-commerce site home page loaded on average in 9.47 seconds and did so successfully 99.78% of the time. The weighted then combined load time and success rate figures earned Newegg an index score of 847 out of 1,000, Keynote says.
Buy.com topped the index for the week ending Sept. 16 with a load time of 4.10 seconds and a success rate of 99.77% for a score of 964. Amazon.com Inc. came in second with a load time of 5.18 seconds and a success rate of 99.89% for a score of 957. And Barnes & Noble came in third with a load time of 5.69 seconds and a success rate of 99.54% for a score of 897.
The average page load time for all 30 retailers on the index was 8.44 seconds, the average success rate was 98.83% and the average score was 736.

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.
