Today's consumer will choose one company or product over another because the perceived value in their choice is greater. People no longer have the time or energy to shop around. Given a need they go to or search for the site that happens to be at the top of their minds at that very moment. They will inevitably choose the site that stands out from all the marketing messages so desperately fighting for their attention. The mind hates confusion.
Simplicity is of colossal importance since long or obscure URLs can be easily forgotten.
The simpler it is the better. Many people attempt to skip the search process and go to your site directly. Thus you will lose credibility. Both your host and domain name are like the cover of a book, and people will likely judge your book by its cover. Remember that perceived truth is more powerful than truth itself.
