Posting full length YouTube videos on multiple platforms as a promotion method?
When it comes to sharing YouTube videos on social media as a promotion method while you're microscopic with only a few videos up, I heard different things form different sources - some say that it's best to just post announcements and teasers on Twitter, Instagram, and Facebook, while others say to upload full length videos on as many social media platforms as possible. I do understand that it's best if the majority of content on social channels of your YouTube channel is unique, but is it a good idea to post full length videos on multiple platforms and than make other content you post on each platform unique - speaking strictly if your goal is growth of the channel and you're still small with only a few videos up? If yes, where can you even post full length videos ? Which social platform for example allows you to post 8 minute videos originally created for and posted on YouTube?
