Recently I have found that promoting our offers through CPMs are quite a success. So, I wanted to focus on its campaigns. But two different companies are charging us differently. What should I do to know which is the correct one?
How much difference they are actually showing? CPM rates varies but too much variation is definitely odd.
One is providing around $0.10 and the other one is $3.5.
Well clearly someone is not charging you right. I suggest that start two small campaigns with each of them and see what happens. A company is charging low CPM doesn't mean that it can't convert.
