Hello Mark, You may want to consider using (facebooks ppc advertising). It is a whole lot cheaper than Google, not as strict as google, and gives you a whole lot more serious targeted traffic from there geo targeting options. Example would be, lets say you were selling craft baskets, gift baskets etc.. you can very tightly geo target that niche right down to a very specific -(place, race, male, or female, age, or to a certain collage even, ect..
Did you know that Facebook has around 38 to 39 BILLION page views every single month, and has arbout 400 MILLION users! I think facebook is even starting to scare google a little?
I think this would be a great place Mark, Especially if your on a shoestring budget of some sort and dont put alot of time into google roght now until you get the right traffic from facebook. Then i would try to convert that traffic to earn some quick Revenue, and then maybe consider trying Googles PPC.
