Adsense Secrets Unleashed - Module 2

First, do not ever pay for traffic from a site that promises you a great deal of traffic in a short amount of time. The traffic that you get will not be targeted, and will be of no use to you at all.
In fact, many of these sites are scam sites, and the traffic that you get will actually be automated traffic, not real traffic. Pay-per-click advertising, or PPC as it is known, is not the same as these sites that promise traffic for a fee.
