I hardly make videos for two of my channels but somehow the CPM is way different for each of them... My one channel has $14 CPM with like 1800 views so it so I'm getting $1.80 estimated earnings. My other channel has about $2 cpm with 3000 views and I'm getting $1.44 estimated earnings. Is there a reason why one is higher than the others? Do you get more cpm for less views or something. These two channels are adsense based.
