We all know that having a fast website is something important for any online business. The main reasons for optimizing your website speed are the improvements this brings to your conversion rate, traffic and bounce rate statistics. Yet, from my experience as the manager of a top WordPress speed optimization company, most people that are trying to increase their page speed, want this because of SEO reasons.
This shows a lack of public awareness about those conversion rate, bounce rate, traffic, etc. statistics. Even though countless studies about these problems have been done over the years by big companies such as Google, Yahoo or Amazon, few of these studies have reached the ears of the run-of-the-mill webmaster. The regular webmaster is highly sensitive to any information relating to SEO, but is turned off by boring bounce rate statistics. This is why most people who end up searching for a speed optimization service are doing it because of SEO reasons.
