1) I really doubt that Brinkbabe91 checked out your channel. There's nothing on your homepage. "This channel has no content."
2) Your 24 subscribers are likely everyone you know. Most can get to at least fifty with just family and friends.
3) I watched your Lea video. 23 seconds in and you've said as many swear words. Let me guess. You think swearing is cool, right? Guess how many female YouTube viewers think it is.
4) You're doing Let's Play videos BUT that does NOT mean you show everything you do. Jump cut to the interesting parts. And remember that lame jokes are still lame and should be cut.
5) As you're doing horror games, you need to show yourself doing the game. Viewers want to see your full reaction and that includes seeing your facial reactions. A little insert of your image in the upper right corner is the usual way to go.
6) Work on your homepage. A) Make an intro video for your homepage that is 30 second to a minute long. First talk about the game genre you specialize in ... then who you are (people subscribe to people, not channel) ... then tell your release schedule ... and then do ONE call-to-action and that is for them to subscribe. Don't monetize your intro video. The intro video is an ad for your channel. Don't have another's ad hurt your ad. B) Get your videos to appear on your homepage. You only have four but they need to be shown there.
7) Increase your release schedule to daily. You're a gaming channel. Let's Play videos are some of the easiest and quickest videos to pump out. It is also what you need to do to be competitive.
8) Once you are monetized, you can use the scheduler to regularly release videos. Always always ALWAYS build up a backlog of videos sitting in your scheduler. Do this not just for vacation time but in case you get sick, your computer crashes, your internet connection goes down, you get writer's block, etc. It also gives you breathing space. If you release a video everyday, fourteen videos in your scheduler represents two weeks of episodes before you have to produce another video.
9) Work on your thumbnails and video titles. Do a YouTube search on how to do thumbnails and video titles. There's a lot of good videos out there about both topics.
10) Subscribe to Tim Schmoyer's "Video Creators" and mine its archive. You can and should spend days in its archive.
11) Normally, I end this kind of a post with "Lastly but most importantly, collaborate, collaborate, and collaborate. You're a very small channel right now but..." BUT right now you shouldn't be asking any YouTuber to do collaboration with you. You only have four videos. You're not even a month old. You're a gaming channel. Before contacting other YouTubers who do gaming videos, you need to show you're here to stay and that you can pump out content. Get your release schedule up to daily and keep at it for three months. After then, you can start to think about collaborations. Until then, most YouTubers won't be interested in doing so with you.
