It all depends on how much a unique visit is worth. If you are selling a service or product and getting good conversion ratios, I'd recommend going straight into PPC (Pay Per Click such as Adwords or Overture). But if your unique visits aren't worth that much - if they do not justify the expense associated with PPC - then try some organic SEO and look at strategic link partnerships which drive on-topic traffic.

First, keywords in the page titles. Then get links. Start off by submitting to directories such as
www.bluefind.com &
www.wowdirectory.com and
www.goguides.org
Then request links from other sites such as niche directories.
And keep on building links.
