Once your site is well-designed, you'll need to promote it to your audience.
Many search engines offer additional advertising packages.
Some of these services will even optimize your pages to maximize the number of times your site gets brought up in a search result. There are other effective ways to market your site as well. If you have company letterhead, business cards, Yellow Page ads or other advertising material, add your URL and email address to them. Consider an additional listing in the White Pages to include your web site. Notify customers of your new site by mail, or use direct email to get the word out.
