I have been at it for about 2 years now. I started on Twitch with gaming and had a decent following already before I started YouTube. I pretty much told them all they have to subscribe to my YouTube channel almost every time I streamed. LOL
You could say I brainwashed them. Then I got into VLOG's, Reactions and Pranks. With every video I reached a different audience because, different titles, descriptions and keywords. If I did a VLOG on my yard work. Anyone searching yard work could find me. If I did a video with my dog anyone searching dog could find me and so on. I have uploaded 536 videos and with every video I have potential to reach new people.
I also use Twitter and Facebook to promote my videos.
I practically spam my twitter with my video links. LOL
I always try to be energetic and entertaining in my videos. Another thing is always trying to put out better quality by using higher quality equipment.
So, far that is what I have done.
I just recently discovered that forums are an amazing way to promote your videos.
Do you just do gaming or what else do you do on YouTube?
