Put Among Us and boobs in your thumbnails and title all your videos with things like "3AM", "ASMR", "CHALLENGE", "PRANK", etc

Kidding of course, but you should advertise your videos to be enticing while showing things related to the actual video, YouTube seems to like bright colours/saturation but don't overdo it, and if a title is too long or not eye-catching enough just simplify it.

Use. The. Description. Don't just put your social media links in and call it a day, the more keywords that can be picked up from it the more your video can be recommended to people or searched up, same with tags (don't listen to anyone who says they don't work).

And a good site to share content on? You're on it, just find the right subs that won't punish you for self promo. Works for some people, others not so much but it's worth a try.
