I have a YouTube channel - all my own copyright, (but it has been demonetised and I'm not quite sure why). [login to view URL]
The copyright belongs to me in all the videos uploaded there. It is relatively successful in terms of number of hours viewed per month, and achieves good reviews/comments.
I also started a podcast recently, which is essentially the same material. [login to view URL] available on iTunes etc.
I hope you can lay out a measurable strategy that would increase awareness / traffic / subscriptions to the podcast (and the YouTube channel).
