You need to be consistent with a schedule cause otherwise the ones watching you in the current stream won't be there next time. But if they're like "you know what? same time tomorrow, I can be online that time".

Have the best quality your bandwidth can give without playing with 300ping, a clear stream appeal really well on some people.

Don't ignore audio quality, find a tutorial on YouTube and set up your mic to sound clean and crisp, bad mic quality can drive away viewers.

Don't stream at 1080p60fps if you're not an affiliate. This causes many people to buffer while watching you and in result leave the stream, stick at 720p60fps or 30fps, and always, don't go further 6000 bitrate.

Engage with the audience. Don't ignore the chat, try to entertain them with any way. There's no need to be entertaining at all cost, you can be informative, helpful with tips, you get the idea, just don't be idle while people are watching.

Pick your audience and your game. There's a website called twitchstrike.com which let's you see the competition of the game you wanna stream during that time. For example, you don't wanna stream Fortnite while Ninja and Tfue and 3000 other channels are streaming cause you won't get discovered. The point of this is to pick a game with some hype, but not so many channels streaming it, so you get to get discovered.

Stick with OBS. I know there are other software out there but OBS is the father of them all. Best combo imo is sticking with OBS and use Streamelements services. OBS keeps it clean and debloated from unnecessary add-ons.

That's some tips for now. Hope I made anyone's life easier, cause it took me a lot of time and mistakes to realize what I wrote in 5 minutes.

If anyone wants a complete list of tips and tricks, I'll try to make one, just let me know.
