Criminals targeted Christmas Eve and shipping cutoff days for delivery by Christmas for fraudulent purchasing, a new study finds.
The North Face knows, and it’s among the fastest performers on a mobile index.
Images are crucial to selling on e-commerce and m-commerce sites. But while web shoppers are often accessing e-commerce sites on reliable, high-speed, broadband land lines from home or work, smartphone shoppers are accessing m-commerce sites on unpredictable wireless networks of varying speeds. A web page with dozens of pictures can be speedily loaded on a PC with a broadband connection; but over a wireless network, dozens of images could greatly slow the load time for a mobile page.
Outdoors apparel and gear retailer The North Face uses about two dozen images and icons on its mobile commerce web site home page, yet that page loads in 7.56 seconds, which is far better than the 13.88-second average for the 30 retailers on the Keynote Mobile Commerce Performance Index for the week ending Oct. 13. Weighting and combining the 7.56-second load time with a 99.29% success rate (also known as site availability), The North Face earns an index score of 949 out of 1,000, putting it in fifth place. 7.56 seconds is the retailer’s fastest mobile home page load time since the merchant was added to the index in May 2012.
The secret to The North Face’s success in mobile performance, even with a home page loaded with images and icons, is the retailer’s use of two mobile web design techniques: data URI schemes and minifying, says mobile and web performance management firm Keynote.
Data URI is a scheme of encoding data within a web page that make up page elements such as images or CSS, a mark-up language used to define pages and denote where elements appear on a page. With multiple elements encoded within a page, no extra HTTP server request is made to fetch the embedded elements as opposed to a request for each element. URI stands for universal resource identifier, a string of characters used to identify a web resource such as an image. Minifying involves removing all unnecessary characters from source code without affecting functionality; this reduces the size of a file and thus shaves off time from the total page load time.
The North Face did not respond to a request for comment.

Keynote 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 mid-sized retailers like Toolfetch.com LLC. Keynote tests the sites in the index every hour Monday through Sunday from 8:00 a.m. through midnight Eastern time, emulating two different smartphones on two different wireless networks: Apple Inc.’s iPhone 5 on AT&T and the Samsung Galaxy SIII on T-Mobile, both using 4G networks. 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. To consistently rank high on the Keynote index, sites must hit availability targets of 99.5% or better and be faster than 10 seconds to load on average. Top-performing sites load in under five seconds.
While 4G adoption among U.S. consumers has been steadily rising, only a fraction of all U.S. wireless connections are 4G. Consequently, retailers benchmarking their mobile commerce site performance against the Keynote index should keep in mind that most of their m-commerce site shoppers will experience page load times slower than those on the index.
