some of you are completely wrong ... if you use ppc programs you will not get unique visitors! just a a lot of visits from the same ip's. if you bought traffic from someone and you received it in a few days, than YES you are right, don't buy traffic, because you probably received it in the same way as ppc (no unique ip's). But there are some the sell traffic from unique visitors (like traffic.wtools.eu) and that's what counts for serach engines! And people, the point of buying traffic is not that you will sell through that traffic, but you will be in the front pages of a search engine and that's what really matter. You should buy from someone a small package ans see for yourself how it's works and if it's bad traffic. I use
WTools Traffic.
