Do you know that you have between three and five seconds to impress the visitors of your blog? If they do not find what they need within that short amount of time, they will leave -- and never come back. Good user experience does not stop at quality design and content. People do not have time to waste; they expect pages to load fast. And search engines like Google may also consider site speed a factor for ranking.
