"The emergence and the fast growth of the web performance optimization (WPO) industry within the past few years is a telltale sign of the growing importance and demand for speed and faster user experiences by the users. And this is not simply a psychological need for speed in our ever accelerating and connected world, but a requirement driven by empirical results, as measured with respect to the bottom-line performance of the many online businesses:
- Faster sites lead to better user engagement.
- Faster sites lead to better user retention.
- Faster sites lead to higher conversions.
Simply put, speed is a feature."
