How do I get more viewers on my stream?

Hello, this is Wiily8 again. I recently asked some questions about YouTube and I was very pleased with the answers I got. I am now wondering how I can drive more viewers to a livestream. I see streams with plenty of viewers and just wish they that was me. So I need some help.

1. Do I need a special title or anything?

2. Do tags really matter while I'm setting up my streams on ps4

3. Is the thumbnail important?

Thanks!
