You need to have a content and keyword rich front page to your site, and when I say front the very root of your site it http://yoursite.com/index.html

If you can't accomplish this using UBB then install workpress, use some of the good SEO plugins, find a good free theme (woothemes is great). Only do this though if you are competent enough to keep it maintained.

Won't you take me to Funkytown?
