First I love the banner design! I think it looks great, but it doesn't tell me much as a viewer! When do you upload? Is it daily, weekly, monthly? Let me know a schedule so as a new viewer I can support you! If you are still figuring it out, say weekly! As it is your banner tells me what you do, and what games, but nothing about YOU and how your channel will help ME is it learning how to get better at Sims? Is it going to be funny sims moments? The more you let me know them ore we can find out!
Another thing is since you are new, some sim games may perform better than others. Look at what's doing the best!
Also you don't have a channel trailer, and I'd recommend you have one. Channel trailers don't have to be a dedicated video, it could just be a video you are most proud of!
Another thing I would do, is create playlists for each game you are playing, so a Euro Truck sim playlist, tank mechanic sim playlist, theif sim playlist, etc. So it's easy for your audience to just binge a game sim type from you!
I see you have playlists, but they're not on the home page! You can edit the homepage by clicking customize channel and change all of these things!
The about tells me more of your schedule:
"Welcome to the S is for Simulator channel! We Post Simulator content 365 days a year. We hope you love the channel! " however, most new users don't make it there, the about is more for YT to see quickly what your channel is about! Similarly to that your channel has no channel tags! Include your name, the sims you covered, and things people might look for when looking up sim games!
I hope that helps! I've seen a lot of channels and think your banner looks great, but could have more! Update your channel, make searchable playlists with good descriptions and you'll do great!
IF I had to give you a grade, I'd give you an C -
Thanks for letting me take a look!
