Advertise in E-zines. Additionally, e-zines usually reach very specific, targeted markets. This is the real beauty of e-zine advertising.

Higher interest equals higher sales percentage.
List your Web site with the search engines. There are many search engines available on the Internet, with more coming online every day. The process of registering is very simple, but can consume a large amount of time. This is especially true when you consider that you will probably need to resubmit your site on a regular basis. My suggestion is that you focus your attention on the major search engines.
