I'm not sure you can prepare some perfect way to get your first one to "take off", I think it takes consistent posting of similar high quality content and then it helps to be a part of communities. Not just joining one and throwing your videos into a promo section and leaving (that rarely gets attention) but actually becoming known. Cause all it takes is a larger channel than yours to share you out and you get a nice little influx of viewers. I have been getting VERY little attention on my full length youtube videos, but the one short I did post got 70 views and it wasn't even very good lol
I need to post more but with live streaming, posting in forums, and trying to do two tik toks a day and 4 yt videos a week, I get overwhelmed. I'm slowly getting into a rhythm with it though and tiktok has shown me the most return of any platform.
