Junk traffic or quality traffic. Junk traffic: You can pay some guys to bring a lot of junk traffic to you, 100,000,000 would bring 1 sales. Quality traffic: If you have a high quality content landing page, you can do SEO, also PPC to sent people to your website.
I suggest using PPC OR Ezne Ads to targeted Markets! You can google the ezine directories for those target ezines!
