If you’ve been looking for compelling data that will help you make a case for investing in mobile performance, this session -- delivered by Strangeloop president Joshua Bixby at Velocity EU -- is a must-see. Mobile web users are demanding. 85% say they expect sites to download at least as quickly on their mobile devices as they do on their home computers. Almost half say that poor performance makes them less likely to return to the site. And one third say they would visit a competitor’s site next. Yet despite high user expectations, m-commerce sites continue to lag in performance, with the average site taking more than 9 seconds to load. Despite the technical constraints of delivering speedy mobile websites, some companies are emerging as leaders. But significant data is still hard to come by. To fill this gap, Joshua has dived into Strangeloop’s customer analytics to evaluate the relationship between performance improvements and business KPIs for m-commerce sites. In this session, Joshua will present brand-new data in detailed case studies that show how real-world companies have optimized the performance of their mobile sites, and as a result have experienced dramatic improvements in key performance indicators such as: Page views Conversions Cart size Revenue
