So I have a quick question about FB ads. When I make a test campaign with $5 budget, I get oCPM cost of around $0.70 for USA However, when I up the budget to let's say $100, the oCPM cost runs up to $2.50 or even more in some cases. I am doing newsfeed desktop ads in USA, see picture here: DAY 1 I set daily budget to $10 and had ok results that would have worked for me http://i.imgur.com/x6MyJXk.png DAY 2 I want to spend more $ to make more $ so I upgrade the budget to $40 daily and the CPM cost almost doubled http://i.imgur.com/EXVdRoH.png Is there any way to avoid this? Everything is the same, just because I change the budget shouldn't mean I should spend triple or even more on CPM cost. Any tips from pros?
