How can this be possible if they aren't associated with Google. It is just false advertising and nothing more, but a trickery for desperate webmasters who would try anything even if it sounds too good to be true. I would suggest to stay away from sites that say 10,000 hits or instant traffic, and etc.
I think they provide you some other menthod to get traffic do google adsense, or use other ppc ,or banner solutions to get traffic. Just so .It's my point.
I saw a video on Youtube where a guy named Traffic Coleman was talking about selling advertising space on the page that you were running your Adwords ads on. One offsets the other, clever !
