After looking at your channel, you have change from minecraft niche to pokemon niche and now to tech niche.
First problem, the niche you chose has super high competition. When you search minecraft on youtube, there's like millions and millions of views. You cannot enter that niche obviously. Unless, you aiming for certain niche in minecraft.
For example:
- Top 10 things you won't be able to find in Minecraft
- Top 3 things you possible won't believe can happen in Minecraft
Do you see the difference of how you can micro niche minecraft into that path? This can apply to any niche.
Now I saw that you change into Tech Review.
This is great since I am quite knowledgeable in Tech Review channel.
First your audio sometimes fade away which can be a turn away a viewer.
Second, whenever you do a tech review, always prioritize the good things over the bad unless you want to focus only bad things which results in a lot of dislike and no company will ever want to send their item for you to review.
Third, show a little bit of text information on your video. People can easily get bored just listening, so add text.
Fourth, make sure to research the gear you want to review especially if you don't own one. It would be the best if you own the product so you can showcase it's functionality personally rather than using other people's video.
I hope that this can help you to really research on your niche and your YouTube channel.
