Do need a niche and how connect with your viewers?

[Kaitlyn Moore]

Hi All,

I've been on youtube for a while now mostly just doing fashion or lifestyle based videos but I don't like sticking to one specific niche as the videos are limited and I like doing whatever I find interesting and that I genuinely would watch, but do I need a niche to grow my channel? And my other question is how can I connect with my viewers more, I always say to leave comments but only like two people do and my viewers aren't my subscribers how can I encourage them to be fans?

Thanks in advance!

niche is good, & in plenty of them you can do different things, like I can go make a video of hiking, a product review at home or a video of an outdoors photoshoot..................good thumbnail designs..........what camera do you use?
