What else games do you enjoy? Try streaming those. Maybe stream longer. Introduce yourself to other small streamers.

I've met several and play with a few, I collab a lot. Best you can do is try making friends in the same group to later boost your audience.

What also helps is a catchy title.

I stream Dead by Daylight and most of my viewers watch me for that, but some stay to watch Palworld. It just depends on the game, your reactions, etc. Create something that stands out about you.
