Loading time not only makes it a very pleasurable experience for the users & reduce the bounce rate of the website but can also really assist your website getting rankings in the major Search Engines such as Google, Yahoo! & Bing.

How I hear you asking?

Well lets use one of the major search engines for example like Google, seeing as though its the biggest. It is believed that the number of pages Google crawls & stores (Google Indexation) that directly correlates to the improvements in speed and also loading time.

This plays on the notion that Google could possibly designate a set amount spiders to crawl a website and its resources. So if you were to optimise your website better for speed then you can improve your chances of pages not being missed & subsequently not being indexed.
