If you want target traffic for sure... I would suggest you look into Google Adwords, its one of the most popular and effective forms of advertising online right now. A lot of big players do it. The downside is that it will cost you about 5 to 50 cents a click depending on the keywords you bid on. A lot of those clicks will go to waste but a 10% rate of customers through these types of ads is considered very successful.
