If you build your own site, they won't necessarily come. You can create the flashiest site in the world, showcase the most appealing products at the lowest prices, and still not succeed. For the same reason one might not succeed outside the Internet. It takes more than just a superficial attempt to create a successful venture.
Many people seem to believe that just being on the Internet is adequate marketing.
That's not true. Whether your interest is to expand your business market, start your own company or promote a personal or hobby-oriented agenda, the same rules apply in making your web site successful. First things first. If you don't already have an account with an Internet service provider, get one. They are relatively inexpensive, especially if you spend a lot of time online.
