Evolution of web performance culture

The main goal of boosting website performance is to improve the user experience. In theory, a satisfied customer is more likely to use a particular company’s services, which is then reflected in business results. However, from my own experience I can say that not every change can be easily converted into money. I would like to tell you how to reconcile these two worlds, how to convince the business that the benefits of better performance are a long-term investment, and how to streamline the development process during the design or code writing process.

Measuring Web Performance
