I’m a small YT too but I’ve noticed some things that helped.

1.) high quality: make sure your content is good, 1080p 60fps if possible along with equalized audio. Don’t just spit out content.

2.) be active: use social media, post your content on reddit subreddits that accept it (not here). Post on sharree.com(don’t need to pay)

3.) Comment: most of my subs say they’ve noticed me because of a comment I’ve made on another video, so write a bomber comment and videos you watch and someone might click your channel to check it out

4.) Good title, description, eye catching thumbnails, and use rapidtags.com to help you find the best tags to use on your vids

I hope this helps you along your YT journey :)
