How to get my minecraft youtube channel to grow?

I have good content. Amazing computer (Record at 75 FPS on max). I have a blue snowball Mic.
I have a good voice. I talk clearly. But I'm just going nowhere. Can you please give me some tips on how to get noticed or to improve my content. I also make video with friends and have a variety of videos. Can you help me with this? Could you also give a detailed answer!
