Question about Youtube promotions and adsense!?

[Chris]

the ads promotions from youtube are no good at all im afraid.
You would be wasting money by buying into it and would get more views by going out and throwing pennies at people with a note attached asking them to watch your videos.

those ads work by adding your video for advertising into an algorithm that determines whether your ad will be played to someone else watching a video else where
And the chances are astronomically small.

Social media.
That is all the advice I get on this sort of thing, and is the same advice I would give.
Slowly but surely, it will work.
Start a blog, do some vlogging on your channel share your videos with friends and family and ask them to share links out too.
That's how it all starts.

Good luck to you.
