First of all.......yeah impressions are page views not clicks.Secondly, the amount u get out of 1000 impressions is next to NOTHING at all. It's a joke really. Dont even bother about getting your impressions high, cuz there's another catch to it. If your CTR or Click Thru Rate goes down real bad, then you're site will be getting what google refers to as LOW PAYING ADS. That is the amount u get per click will be drastically reduced. so yeah, unless you're site is getting like thousands of visitors per day....dont bother about impressions or services which pay you based on impressions
