How site speed affects your user engagement

by Josh Fraser on August 28, 2012

One of the key differentiators of Torbit Insight is that we offer the ability to quantify the value of your website performance. No other product on the market allows you to correlate website speed and revenue. For years we’ve heard stories from companies like Amazon that tell us that one tenth of a second equals one percent of sales. These public case studies are great, but what about your website? We built Torbit Insight because we wanted an easy way for everyone to know how much speed matters. There’s something incredibly powerful about seeing key metrics based on your own data from your own visitors. We’ve now helped hundreds of companies change performance from being just a technical metric (something your engineers worry about) to a business metric that influences real decisions at your organization.

If you use Insight you may have recently noticed a new addition to your dashboard. We added a graph that shows how user engagement is affected by the speed of your website as measured by the number of pages visited per session. Once again, the data tells a clear story: speed matters.

Showing the correlation between speed and revenue has always been a key focus for us. For example, we have a graph showing the correlation between your site speed and your bounce rate. For internet retailers, we offer conversion tracking that makes it easy for e-commerce sites to track the correlation between website performance and actual sales. Other sites have used our conversion tracking to track other activities like someone requesting a demo or signing up for a mailing list. Advertising-based businesses tend to care about other metrics like the number of pages viewed per session. More pageviews means more ad impressions which means more revenue. This new view should help give more visibility into this important user engagement metric. On the x-axis you can see the various speeds at which visitors experienced your site. On the y-axis you can see how many pages your visitors viewed across their session at each of those speeds. In the example above, you can see that there is a huge advantage in having 1 or 2 second load time. For this particular site, a 1 or 2 second load time ensures that an average visitor will view 23 pages per session. In contrast, if the site takes 15 seconds or longer to load, an average visitor will only view 5 pages per session.

The exact numbers and corresponding graph will vary from site to site, but most sites will see a strong correlation. When your site loads faster, people stick around longer and view more pages. Once you know how much speed matters for your site, you have a much better way of knowing how much to invest in site performance, whether that’s the money you spend on developers or on performance-related technology like a CDN or Dynamic Content Optimization.
