Slow pages hurt mobile user metrics, from bounce rate to online revenues and long-term user retention. At Radware, we wanted to understand the science behind this, so we engaged in the first documented study of the neurological impact of poor performance on mobile users. Your takeaway from this presentation is hard data that you can use to make a case for investing in mobile performance in your organization.
Based on similar research performed on desktop users, our study involved using a groundbreaking combination of eyetracking and electroencephalography (EEG) technologies to monitor brain wave activity in a group of mobile users who were asked to perform a series of online transactions via mobile devices.
In our study, participants were asked to complete standardized shopping tasks on four ecommerce sites while using a smartphone. We studied participants during these tasks, both at the normal speed over Wifi and also at a consistently slowed-down speed (using software that allowed us to create a 500ms network delay). The participants did not know that speed was a factor in the tests; rather, they believed that they were participating in a generic usability/brand perception study. From the data, we were able to extract measures of frustration and emotional engagement for the browsing and checkout stages of both the normal and slowed-down versions of all four sites.
This presentation, shared by Radware Web Performance Evangelist Tammy Everts at the 2014 Velocity Conference and the CMG Performance and Capacity 2014 Conference, provides a deeper understanding of the impact of performance on mobile users.
