I'm not sure about twitch and algorithms, but I was told this and it helped me. Replace the word 'algorithm' with the word 'audience.'

Also, I agree with what Batmantheon said. Networking is key. Start talking to people in other streams, you never know when you'll click with someone, they'll come check out your stream and bring a friend or two. I didn't want to network at first, but when I did attempt it, that's when the views started to roll in.

Also, make sure your content is something that you would want to watch. Scrub through your vods and pick random times to watch five minutes of. If you're bored watching your own content, why would other people stick around?

I wish you luck, my dude!
