Top ecommerce sites around the world are slowing down
A report from Radware, an applications delivery and security firm, suggests that page load times of the top 2,000 online retailers has risen substantially over the past year.
Because pagespeed “affects every conceivable business metric, including page views, bounce rate, conversions, customers satisfactions, return visits, and of course revenue”, this is something that online retailers cannot afford to ignore.
Radware tested the top 2,000 ecommerce sites, as determined by Alexa, and found that the median load time for initial page load of a homepage has increased by 22%. In December 2012, the median load time was recorded at 7.25 seconds, compared to 5.94 seconds the previous year.
Group the top 100 online retailers together and the median load time increases to 8.23 seconds. Joshua Bixby of Radware commented that,
“if this slowdown rate goes unchecked, we will see median load times of 9 seconds or more, which is simply unacceptable for online shoppers.”
The report also found that only 25% of the top 2,000 ecommerce sites used a content distribution network (CDN), a service that serves static images and files from servers close to where the online customer is located, therefore decreasing download times. Also, between 13-22% of these sites have yet to implement “simple performance-enhancing techniques”, like browser and database caching, or minification and grouping of static files used for styling page elements, for example.
Why are ecommerce sites slowing down? It could be that worldwide Internet bandwidth is simply increasing as more and more users are streaming movies and music, something that has again grown hugely in the past year. There’s simply more traffic on the Internet.
Bringing Web browsers into the equation, Firefox recorded the fastest median load time at 6.64 seconds, followed by Chrome at 7.09 seconds, and Internet Explorer 9 on 7.25 seconds.
