The obvious one way is to SEO your site so it earns (and that's the word for it) a TOP postion in GOOGLE and other search engines.
But you can -- and should -- also include the URL on all your business cards, letterheads, invoices, emails, and whatever media ads you run. This will encourage people to reach your site directly rather than because of a search word or phrase. To some extent, too, it will encourage Google et al to notice you.
One other idea is to get your site included in various related directories. Many are available free, others have a (relatively limited) charge.
The main point is to let as many people as possible know that you have a website.
