It will, but it can also disrupt your rhythm if you end too early. Sometimes you might have to fluctuate to accommodate that need. (Maybe stay an extra half hour here or there,) depending on your broadcast flow. Sometimes if things are dry, call it early. But if things are buzzing you might want to extend things.
Most of my regulars stay. Sometimes new people come in and stay. Since people know when to expect me, they linger. I did an 8 hour stream once and people stuck around for the duration.
Regardless if you stream one hour or ten, if you broadcast on Twitch you’re a real streamer to me.
I see no distinction.
And viewership depends on the game and who is streaming what, honestly. If it’s a hype game like the Star Wars Battlefront beta, I was averaging about 20-30 viewers the days I’d stream it. Then it would dip between 10-15, depending on how much action was going on at the time.
(You’d be surprised at how many people will leave if you’re in a menu, lol.)
When I first started MGSV, I had about 50 concurrent. Now it can dip between 20-30, depending on who else is streaming and if my regulars come in. I say ‘depending on who else’ because if it’s a big name streamer and the game just launched it will affect potential people being exposed to your channel, but that’s another beast entirely.
Sometimes I’ll have more of my core base present when I stream. Sometimes it’ll be a Mod wall. Other times a bunch of new people will come in so it varies.
EDIT: Honestly, concurrents matter. But not as much as growth. If you have 20 concurrent but no conversions, that’s a problem. Your goal should be to get at least a certain amount of followers whenever you go live in the beginning to build your base. (For example, my follower goal is 10 every time I stream.)
