oops, I highlighted that message
I would say its all about google and your chosen niche. Find affiliates with similar topics and exchange links with them. Submit your site to directories. Register on as many competition sites as possible, and have your sig / profile homepage with your site in it and try to post like a regular. The more incoming links you get, the better google likes you (legitimate links mind you) so the higher you'll appear in the search results for your keywords. Also, the sig thing has the advantage that if your a decent memeber people will be inclined to follow the link. I hope that makes sense.
