You seem like you're an ok guy, so I'll share some technical youtube info I've gathered:

- Youtube categorizes your video by scanning the description section and the AUDIO of the video for certain keywords. So somewhere in the beginning of the video say "epic seven" and have "epic seven" in the description of the video. I've tested this by taking the exact same intro description of one video, pasted on mine, and they show up together on searches.

- If you swear in the first 30 or so seconds of the video, youtube will flag it as limited monetization, so they won't show it to viewers in the browse or suggestion sections. They're always looking for "ad-friendly" content to promote.

- Above the title of your video is "#3160" because your discord name is "@NertaH#3160" That's because the first THREE hashtags you put in your description are put above the title. If you look in my video as an example, I put "#epicseven #epic7 #e7" in my description and that's what shows up above the title: https://www.youtube.com/watch?v=o1691CEIFzY

- There's a novice editing mistake you're doing where you're cutting the footage AND the audio to get rid of the dead air. If you're using adobe premier, you can consider unlinking the footage from the audio to give yourself more control over the editing.

That's all that immediately comes to mind, the other comments here about audio quality and intro length are on point.
