I'm pretty new to the google adwords, and to begin with I have been playing around with one paged website. I have no background in this at all, first two days when i created the keywords I saw the impr.# going up and also the click #. since friday I have been working on adding effective keywords, I see the impr # has increased toward the ad group and few clicks, this is where I'm confused. Under analytics tab I see zero visitors, why? I mean at least it should register the "few clicks" that took place right?

its reason may be the same ip visitors, means to say, you were the visitor, therefor the zero visitors showing
