what if I don't advertise?

Some great tips already. I would say follow the advice so far until you are confident that your conversion rates will stand up. Then look at AdWords but only if you make a profit on any dollar spent and if you still have capacity after you have maxed out your organic traffic.

If you're not going to advertise but already have a site set up, I'd recommend using Clickbank to get others to do the promoting for you.

I totally agree with Wayne. Adwords is effective but is incredibly expensive. You can get hits to your site, like Wayne has put.
