Hey there,
You have noticed that your CPM is quite low and are wondering if it is possible to raise this for your channel.
As
@RonaldWallace pointed out, your CPM depents on a lot of factors. The country you live in, time of the year, in which country your video is being displayed the most and the contents of your video. Due to a lot of these factors its generally very hard, if not impossible, to raise your own CPM.
A tip, at the end of the year (20th of december - 1st of January) CPM's are generally quite high, so uploading more videos in that period can be really good!
I hope this answers your question.
