Before choosing a platform, I read a lot of different reviews, opinions and everything in order to find a platform that would make it as easy as possible to promote myself and my streams. Many people recommended Twitch, but there is still no result.

Maybe your content isn't super high quality so that people actually want to watch it?

To be honest, this is quite a complex topic because every social network and every platform has different algorithms, promotion strategies and all that. Speaking of Twitch, I can recommend Streamerplus.
