I still don't get it... I think that eCPM ~ (earnings/impressions)*1000 is money that they will pay for 1000 impressions because it is called : Cost per 1000 impressions?...Or do they pay this money if I show single advertiser 1000 times? And how much money I get from it? 1000 impressions = 1 click?
Could someone who knows for sure how it works explain how this works to me please...
