@nprofile1q... as much as I hate to come across as negative/critical, 'followers' on any social platform means nothing as they very rarely covert into 'fans' and even more rarely convert into purchases of your music.
A 100 people will give you a 100 different 'strategies'.
I would just focus on the platforms you actually want to invest time and effort into and ignore anything else as you'll end up being a social media admin rather than a musician.
