if there is no click in in your account only lot of impressions.. then Google pay or not any cent to us ??
I have read that google may only par per impression if your site is really really popular otherwise they dont.
I believe they don't. I just went through their relevent pages but couldn't find any thing that says about this.
yes they do they have a complex algorithm for this formula you can go to your account the calculation is there in my case my earnings is adding even though i only get impressions
Yes, Google do pay for impression (CPM) in Google Adsense but the rate is pretty low. CPC pay is higher.
I don't think site should popular for display Pay for impression ads, becasue of when i start blogging some days my Adsesne clicks 0 but i can get $0.2 or like that amount. At that time my daily traffic less than 200. So i don't think site shoud be popular for disply Pay for impression ads
