EPC, Impressions & CTR

[activeco]

Let's say we have two identical pages showing the same ads.
Due to some better marketing one have 2.000 impressions per day, the other one only 500.
But the first one has badly positioned and unattractive ads layout so they receive exactly 100, the very same clicks, each.

Which one will earn more money, if any?
Why?

I've tended to find that ad placement changes numbers by 10-20%, so clearly your 2000 impression site will be the bigger earner, all other things equal.
