I am third in, and agree. Well shot and edited.
Unfortunately I will beat my dead horse. New channels on Youtube have little to no where to go.
As of early 2020 there was roughly 37 million channels on the platform. A rough estimate I found was 14 BILLION videos are on YT right now. The numbers are staggering.
What I am getting at is, hoping Youtube can suggest your channel or videos is near an impossibility.
I am not trying to discourage you, just the opposite. You have to be much more creative in promotion. I have posted on Reddit, Twitter (the best one for Youtube IMO) and Facebook (the worst IMO)... and even Tumblr for over 5-6 years. I never have put much into it other than a post with some hashtags, so I am not surprised at the lackluster results.
For you, find your niche, research it. Where do people go to see your kind of content, whether it be blog, video, article or podcast. Find a few that are successful, see if you can find anything unique about them, maybe how are they doing so well. Finally, if you are bold enough, hit some of those channels up and see if you can do a collaboration with them. Your videos are well done, so there is a good chance they might consider it.
Good luck with everything, welcome to the board!
