How do I get more views on youtube?

[Billy]

I have a youtube channel, and enjoy making videos when I have time, but none of my videos get very many views. I even have hem monetized, and the ones that are 100% all my own still don't get hardly any views. I'm just curious to know why I get so little views. Are my videos not good enough, boring, stupid, or do they just not get into main stream where people can see them? I have 84 views total on my channel with I believe 4 videos total. Any tips to get more views and make a little cash?
How exactly do you put a link into another videos comments, whenever I try it it shows an error...

post a link to your video on comments on another video that has alot of views e.g gangnam style, love the way you lie..and u get it. Gud luck

Post the link to your channel/a video on this question, or on any of your social media accounts. Should get more views.
