The original reason I asked is because there are a lot of ways to send a ton of traffic to a website, but the question is... is this traffic targeted? i.e. are they interested in the content of my website?
I have only briefly looked at adgridwork.com, but I will examine how it works when I get a chance... anyway, it may be very good at sending you quality traffic, but only time will tell, so keep your eye on what happens
