There are a lot of things you probably didn’t know about website usage, online purchasing and mobile. For example 51 per cent of online shoppers in the US say that site slowness is the top reason they’d abandon a purchase.
Tammy Everts has put together an amazing list of Web performance statistics on the radware.com website that includes some intriguing observations. In her post she talks about user experience and expectations, mobile user habits, page speeds (in both the US and the EU), page size and composition, performance best practices, network performance and finally browsers. She also supplies sources for most of the statistics.
It’s a truly impressive list of stats with a number of gems.
When it comes to online shopping:
Mobile users are also more impatient. According to Tammy’s stats 85 per cent of mobile users expect pages to load as fast as or faster than they load on the desktop. And mobile users are more likely to go to the full site rather than use an app to shop:
When it comes to page speeds, he median leading ecommerce site takes 5.3 seconds to become interactive (i.e. render primary content “above the fold”) and 8.56 seconds to fully load. This represents a 26 per cent slowdown since spring 2012, when the median page took 6.8 seconds to load.
The reason is probably due to the growing size of Web pages. Tammy states that the average web page has grown 151 per cent in just three years. At the end of December 2013, the average top 1,000 web page was 1575 KB. When the HTTP Archive began tracking this data three years ago, the average page was 651 KB. More than half of this page size is due to images. A whopping 804 KB per page is comprised of images. (Three years ago, images comprised just 372 KB of a page’s total payload.)
These are just a handful of the stats you can find in Tammy’s post. Go check out the rest of them here.
