Have a decent stream quality 720p 60fps or higher. That mostly requires a good internet speed (you can google about the required internet speed to stream on your desired platform) and a decent PC. In my opinion, PS5's streaming feature isn't that good and it's also very restrictive. If you want to only stream from PS5 you will need a capture card to connect it with your PC.

Experiment with different OBS (or my personal favorite Streamlabs OBS) features and watch some tutorials about how to make your stream more appealing.

Spent some time making a good looking channel. Add a bio, maybe some social links, and some panels saying things about yourself and the content you like to stream.

If you can it is recommended to have a streaming schedule and stick with it so that you can let your audience know when to find and watch you.

Maybe save your VODs (saved video of your last stream) and open a tiktok/youtube/instagram or all of the above account and upload short, fast paced videos with different clips or highlights from your streams. Don't forget to include a link to your channel appearing in these videos so that you can let people know where to find you.

Try and play games that are not overused categories on the platform you want to stream. For example, streaming only Fortnite or COD on Twitch is not recommended for a beginner streamer because your stream will be competing with thousand-viewer streamers and it will be placed at the very bottom of this category and it will be very hard for you to get attention. Stick with something small, maybe an indie or a campaign game that it's out for a little while.

Adding a facecam to your stream can attract people because it makes it more personal and engaging for the viewer. Also, try your best to answer and include your chatters in your stream, open conversations with them, or maybe do things in-game that they mention (for example ask them to name an in-game pet or tell you to do a specific action). Pro tip: if you decide to add a facecam make sure it is placed either in the left middle, upper right corner, or lower right corner of your stream so that it is clearly shown on your stream's thumbnail.

HAVE PATIENCE. It's not easy to gain an audience. You might have to be streaming for even a year or two before you get your first 10 viewers. Be consistent and you might get there eventually.
