How to maximize CPM?

I'm wondering how I can get the most out of youtube's CPM... Should I have every ad type checked or will just having true view only be better for videos? I noticed for instream ads they don't receive many views but they are sometimes higher in CPM.

If I have a short video should I even include an instream ad or just set it as a true view?

I've had a video with 734 views, 780 minutes watched and received $2.89. My other video has 1511 views, 2390 minutes watched and only made $0.64. How is that even possible? They are both on the same topic of pokemon. Both are on the same settings... Just one has higher CPM than the other for some reason?

Does anyone know or is the keywords I'm using? I'm thinking the views have to keep coming instead of all at once?

No way to maximize it, just deal with it.

Anything you do will be negligible at best.

get more visitors to the higher paying video

I have the same case and I don't know why!
I've a video watched 1099 made $10
Other watched 15000 and made $7
BUT
How can I know the CPM of my keyword?

Just check your analytics..every piece of information you'd want to know about how much you're making and why is in there...

I can't realize how the money comes, From clicks or CPM (cost per mile or impression)
