I would say tutorial and search based niches are better for you then. If you try to get recommended by youtube or on the homepage you have to create like funny, entertaining content and if you are shy its more difficult and as a new channel its harder to succeed in suggested based Content, because when you start out with 0 views, 0 subs its easier to get views on search based content in my opinion. Or you use a view bot ( custom made) then you can get into recommended easily!what are your videos about?
animation ? reaction ? tutorials? reviews?
can you suggest a good theme/niche for me to start on youtube? I'm a shy person btw
