Best Buy Does OK, Costco Tanks. When Keynote Systems started looking at the mobile sites from major retailers late last year, the veteran mobile and Web site test and measurement firm knew that these sites would be a lot slower than their wired Web counterparts. But some at Keynote were caught off-guard by just how slow some of the major retailers’ mobile sites were. To put this difference into context, Keynote argues that a wired Web site should, on average, be able to deliver a page—especially the site's homepage—within two seconds. For mobile, Keynote said, users should tolerate sites that are about twice as slow, or about 4 seconds on average.
In its examination of 10 major E-tail sites—Amazon, Barnes & Noble, Best Buy, Costco, Dell, Foot Locker, Musician’s Friend, Sears, Target and Walmart—the very fastest site (Best Buy) averaged more than twice Keynote’s acceptable slow estimate, crawling in at 8.3 seconds. Again, that was the fastest mobile site. The slowest site delivered its average page in 34 seconds. Keynote officials steadfastly refused to identify which site was the slowest. That said, points made by Keynote while discussing the study pretty much eliminated all of the tested retailers other than Costco from being candidates for the slowest performing site.Read more...
