Whenever you post to a discussion board or forum make good use of your signature. It's simple advertisement to include a link to your Web site in your signature. If someone is interested in what you have to say or in finding out who you are they will click on the link in your signature and visit your Web site.
Before posting links to your site in your main messages or answering questions and linking to your site, find out the rules of the board. Some board and forums don't allow advertising. You don't want your site to be considered spam. Then no one will visit and you will be kicked off the board. You might want to consider lurking on the board for a little while to see what kinds of thing the regular posters post before you do any posting yourself, just to be on the safe side.
Write Articles
Keep your Web site fresh. You can do this by adding something new every week, every other week or every month. The more often you update your site the more reason your readers will have for coming back to see what's new. Whenever you add something new to your site write a newsletter to let your readers know you've added something and they should come have a look.
Pay For Advertising
Pay to have your banners and buttons or text links added to other people's Web sites or newsletters. You may not want to take it this far but if you are really serious about making your Web site popular you may need to.
If you want to ensure that your site places at the top of the search engines you may also want to consider paying the search engines. Many of them offer programs where you pay to be placed higher to the top.
Lycos has a really good "paid inclusion program" and "pay per click" program. Both are good for increasing your site's traffic.
