At Rigor, we want to show e-retailers what all of these numbers reveal about the total potential web performance possesses to increase ecommerce sales for the individual retailer and the ecommerce market as a whole.
The following points provide the pieces needed to put together the big picture revealing what the ecommerce market would look like in a utopia of optimization and lightning fast sites:
- Google engineers found that users begin to get frustrated with a site after waiting just 400 milliseconds – literally the blink of an eye – for web pages to load. (Source)
- Amazon found that shaving 100 ms off of load time results in a 1% increase in sales (Source)
- The average load time for ecommerce sites is 10 s (Source)
- Total US retail sales for 2011 were estimated at $4,155 Billion; Ecommerce constitutes $194 Billion, or 4.67%, of those sales (Source)
What the Average E-Commerce Site Could Achieve
Let’s start with the 10 s average load time statistic. If the average site takes 10 seconds to load, and users begin to abandon pages after 400 ms, this leaves room for 9.6 seconds of improvement to the average site.
What Performance Optimization Could Mean for E-Commerce as an Industry
With a bit more basic math, we can determine the sales gains the ecommerce market as a whole could achieve if ecommerce sites were as fast as users would like them to be.
Using the Census data from 2011, we can see that total ecommerce sales were $194 Billion. If ecommerce sites could theoretically increase sales by 260% as previously calculated, that means, as a whole, the ecommerce industry loses $1/2 Trillion / year due to poor performance.
$194 B + $504 B = $698 B
$698 B / ($4155 B + $504 B) = 15%
Now, I realize that we do not live in a site speed utopia and that this model is idealistic in assuming zero tradeoffs, but it is interesting to consider what the ecommerce industry would look like if the average load time for ecommerce sites were 400 ms–the load time that reportedly would be satisfactory to impatient internet users. Moreover, these numbers show us the great potential the web performance industry possesses to help ecommerce companies exceed revenue and growth objectives by satisfying the universal need for speed.
