Free US visitors to your site - 100% free

I don't know if this site really helping you out with your alexa rank, but i only try it for my PTP link .. for trial :) well its not harm to try something for free rite ??

 the thing that you need to do its visit this link and fill the form

1 x24 they will approved for your request and the visitor will start came! 500 visitors not much but i think it will means something revisitors site already runs for several years and its good site tough for you to increase traffic, they also provide specification if you want visitors for ALEXA or GOOGLE thingy, so they can divide the visitors base on safe traffic or not ( i assume )

but i believe for you who intend to use this for google adsense site... DONT!! dont do that, its not safe i believe it will not safe traffic

so enjoy
