As CXO at SpeedCurve, I help companies understand how visitors use their websites. I've spent the past two decades studying how people use the web, and since 2009, I've focused on the intersection between web performance, user experience, and business metrics. My book, Time Is Money: The Business Value of Web Performance [O’Reilly], is a distillation of much of this research (but there’s always more to be learned). I co-curate WPO Stats, a collection of performance case studies.
