A great web site is like ringing the dinner bell...
When one door opens, there may be a customer coming through it. If you want them to walk them to bite, you need to do a good job of advertising on the internet. Period.
Have you ever noticed that some so-called web designers make sites that are about as bad as a stick through the throat? Don't get burried in mundane - get something that screams.
Did you know that some people out there are up to no good? Don't let your site traffic be a body bag for malware or viruses. That stuff will kill 'ya - and your business.
Web metrics are more than just how many people end up on your site. You want the juicy details. Don't use a service that delivers like the local butcher shop does meat. Very rare.
