Data Monday: E-commerce Performance

by Luke Wroblewski May 21, 2012

Speed matters online. Study after study has shown that even 100 millisecond delays in load times negatively impact user experience and conversions. So it's no wonder that e-commerce experiences are particularly susceptible to performance as these recent bits of data illustrate.

  • The average Internet connection speed around the world was 2.3 Mbps by the end of 2011. That’s down about 14% from the previous quarter. (source)
  • If a page load takes more than two seconds, 40% are likely to abandon that site. (source)
  • The average impact of a one-second delay means a 7% reduction in conversions. For the $100,000 per day ecommerce site, a one-second delay means $2.5 million in lost revenues in a year. (source)
  • Sales at Amazon increase by 1% for every 100 milliseconds it shaves off download times. (source)
  • When Shopzilla decreased load time by 4 sec, they saw a 25% increase in page views, and conversion rates went up 7-12%. (source)
  • Google Checkout’s mean payment processing time was .26 seconds in a recent study. This makes it the fastest payment gateway online. (source)
  • Paypal, the most popular payment gateway, had a mean transaction time of 1.46 seconds. (source)
