Hello guys
So far I have been focused on CPM since I started, I have not yet done any CPC campaign since I was buying mobile redirect traffic for the most part
Now I have this probably stupid question for some of you but necessary question to me:
if you are paying 0.03 - 0.05 for a click, your CR should be higher than when buying on CPM basis , right? - since for CPM you are paying much less per click
am i right? wrong?
any help would be much appreciated

No, not really ...
Sadly not. It's just another way of achieving the same thing.
Generally, which one works better varies by traffic source, geo, and other things. If you're on a new traffic source and not following an experienced person's guide, try both and see which works out best.
