I'm just curious about CPM is that how much I can make per 1000 views? Because obviously it's saying around $4.00 CPM but in reality I know I made a few pennies. I know impressions don't make a lot of money it's usually your viewers clicking your ads if they're interested. Forgive my ignorance I'm just a little confused with the CPM vs. the actual amount of money I made. Is it some weird calculation or something?
