Site promotion is becoming more and more important as the number of Web sites increases. Contrary to what some people think, you can't simply tell search engines like Google just where you'd like to show up. All major search engines look for relevance because if the people conducting searchs can't find the sites they want, they'll just move on to another search engine.
You'll need to consider promoting your Web site just as much as you'd promote any other kind of business. This may mean advertising on search engines just as it might mean advertising in your local newspaper, regional magazines or special-interest publications. Of course, you should have your Web address and email contact on every piece of printed material.
I have a working relationship with Google and can set up an account there to place your ads in the most appropriate keywords.
