I'm checking my Adsense reports and I see that I have 100 impressions on one of my sites. However, I was working on this site and was refreshing it many times, as I was trying new things out and was implementing new design. I wonder if I can have e.g. 50 impressions from just one IP - my IP when refreshing my site many times? Or does Adsense count one IP as one impression only?
