Hey mate, Starting with youtube is not so difficult
the first thing you need to do is to Find your niche.
And that should be very precise not general.
For Example : Only one game or maybe only one character in the game.
So you need to catch one of the subtopics of any general topic and keep making videos on that for few months.
You will eventually get the attention of the people searching for that specific subtopic.
You need to keep doing this until you get 100+ subscribers. DO not get distracted, Its only the beginning of your youtube.
As soon as you cross 100 subs mark, you can start to cover more subtopics while being under the same Topic (Same game with diff characters or different mods).
Remember you have to keep making videos on your targeted topics until you get 1000+ subs, thats when you can start concentrating on what the audience wants. By this time you will be experienced enough to know what to do in order to grow your channel.
One more big tip is keep digging for keywords in TubeBuddy everyday, and always use Keyword with rating more that 40 in your videos.
