Experienced in IM but just started doing youtube (adsense)

I have a channel that is just mostly funny videos. Nothing niche specific. But my earnings are low. I get about 15k views a day now. Not a lot I know but I just started for a few days. But I am getting about 0.3% ctr. $0.5 cpc. rpm is $0.5

It seems a bit lower than average? Average is about $1?

Yes I think that is extremely low. Aim for atleast $2-3/1000 views.

Yea most of my visitors are from US. So I really don't understand. But it is only a few days. I see a slight increase for today compare to yesterday.
