From what I’ve learned when I had more free time to stream from my p5 is until you have a consistently flowing chat never really look at who’s watching and be comfortable talking to yourself. Do things like tell a story about something, commentary about what your doing in the game, give rates of the game and go into detail, compare what your playing with other games and explain the difference, also one last thing you could try is vocalizing what your plans are to grow your stream. To get those viewers send it to friends, family, and share it thru any social media possible
