Although the Internet is a wonderful place to promote your new website, many people fail to consider some other great advertising methods.
Most businesses spend a considerable amount of money each year producing business cards, letterhead, and other promotional material. These days it's rare to see any of these materials without Web and email information on them. By printing your email address and home page URL on all your correspondence and promotional material, you can reach an entirely new group of potential visitors.
Even your email signature is a good place to promote your site. Just put in a link and the title or a short description, so that everyone you correspond with can see what you're publishing on the Web.
When you're promoting your website, the bottom line is lateral thinking. You need to use every tool at your disposal if you want to have a successful and active site.
