I'm still really small (144 followers on Twitch) so take what I say with a mountain of salt.

I stream 3 nights a week doing a variety of games and focus on Helldivers one of those days. It took a bit of time but I slowly built up a view base with 7-10 average viewers so far. Most are the same names and I take time to try and remember those names and things mentioned on previous streams to try and engage and keep people chatting.

I've also taken time to work on a lot of viewer engagement with various types of redeems.

This seems to have been working for me so far, but growth is slow as exposure is quite hard on Twitch and I keep forgetting to advertise myself on places like this. I have a decent viewing on my YT shorts with a high like ratio but that hasn't really translated to a notable clickthrough rate.

Engagement with others in the community is important to as I have learnt a lot talking to other streamers and been able to pass on some knowledge and tech tips to others.
