Performance is about improving conversions
Retaining users is crucial to improving conversions. Slow sites have a negative impact on revenue, and the opposite is also true. Here are some examples of how performance has played a role in making businesses more (or less) profitable
Performance is about the user experience
When you navigate to a URL, you do so from any number of potential starting points. Depending on a number of conditions, such as connection quality and the device you’re using, your experience could be quite different from another user’s.
Performance is about people
Poorly performing sites and applications can also pose real costs for the people who use them.
As mobile users continue to make up a larger portion of internet users worldwide, it’s important to bear in mind that many of these users access the web through mobile LTE, 4G, 3G and even 2G networks. As studies points out in this study of real world performance, the cost of prepaid data plans is decreasing, which in turn is making access to the internet more affordable in places where it once wasn’t. Mobile devices and internet access are no longer luxuries. They are common tools necessary to navigate and function in an increasingly interconnected world.
Total page size has been steadily increasing since at least 2011, and the trend appears to be continuing. As the typical page sends more data, users must replenish their metered data plans more often, which costs them money.
