Your channel URL is: UCqBRy4M5Pm7Jz7sOz_h5tjw
If you haven't gotten a proper YouTube URL, I suggest starting there. After that, go into your video manager and refine your video information. Get some proper titles that don't have "Epic" in them, add tags that relate to the video but are also something that people look for (For your dog video, use tags like "dog" "dog prank" "cute" stuff like that), and upload more! The longer the breaks between your videos, the less likely people are willing to subscriber. Make content and they will come.
