How to get more subscribers?

First i would suggest that you name your videos differently (add something that shows the type of gamer you are, and what happens in it. For example, "Starwars Battlefront #1 - Insert title here), and have better thumbnails (You could have a picture of the game you're playing and then the number (or part) that you're on in the series. Also you should talk in your videos, because if you don't your viewers won't to come back because there's nothing that make you different from the other youtubers (Unless you're the best gamer on youtube). I've noticed that the distance of your videos are far (What you should do is post a video every day to keep people watching cause if you "every now and then" they won't subscribe they'll just look at you're page for more videos. Lastly here are some games you should play. Minecraft (It's one of the most popular on youtube), any game that just came out (be the first), 7 days to die (It's a good game to play with friends). That's all for now and i hope this helps.

Yes what Cloe said, Share your channel, let google index your video's, and try to get it around on social

Share your channel on Facebook, Instagram, twitter whatever you have and ask friends to check it out

I'm a competitive gamer and a somewhat successful YouTuber. The problem with YouTube is, there are So many people in the community making videos. You need to stand out from those people, the way you stand out is beyond me. You could play odd games, you could have a unique or interesting personality. Once you get that down just stay active. If your not uploading once a day people will go to other YouTube channels to full there need. Always set a goal for your subs too. Say "can we get 10 likes" and if you do. Next video try 15 likes and so on. Don't get to stressed on it. Just have fun with YouTube.
