How fast is 50 milliseconds? The blink of an eye? A flash of lightening?  That is how long you have to make an impression on your customers that visit your website.  A Canadian study given in 2005 asked some volunteers to rate a website after only seeing them for 50 milliseconds.  The researchers then discovered that the conclusions that were formed in that quick initial assessment were validated in a longer review of the site.  So, almost as quickly as the eye can see it, a judgement is made on how good your website is.
