This isn't bad and it's probably the sort of thing I saw a year ago before embarking on my YouTube channel. But I have to say, it's no where near as easy or as simple as that infographic. The reality is much more different.
About 9 months ago, armed with information far more detailed than this infographic, I embarked on my YT channel, which is a review channel in a toy niche.
I'm a professional filmmaker by trade, so I have 15 yrs experience and know how to make a high quality video, so I had that going for me before I began.
Plus I have a lot of pro equipment, so I can assure you, my content is better than most.
I can tell you that even by using correct keywords, SEO, titles, desc, tags - Employing annotations, cards - Even buying a few K views to get a ranking, having very decent content - There's just no guarantees that you will make it with any success at all. I have over 80 videos, most of them are decent - They're consistent, been uploading at least once per week - But have still not tasted success, not even close - And I've been working on this full time.
So I'm afraid to say, this "YouTube bandwagon" has a few wheels off and I am out of ideas on how to get it rolling.
