another thing to look out for with Advertising networks is when they hide impressions.
For example, it makes them seem like 'the good guys' by allowing us to automatically revert to another advertiser when we specify a certain CPM limit. But the way they jip us is by not showing the real 'impression' number.
example : we generate 1,000 impressions... but their software only recognized 700 of them.
