When I think "successful social media marketing" I think of some kind of podcast or blog... say

https://www.flightradar24.com/blog/avtalk-podcast/

or

https://multithreaded.stitchfix.com/blog/ https://www.stitchfix.com/men/blog/ https://www.stitchfix.com/women/blog/

(e.g. it was reading about machine learning at Stitch Fix (SF) that I felt solidarity for them and became a subscriber)

That aviation podcast is like a freight train, but that is because they have been doing it so long.

If there is a royal road, it is to pay someone and ride on their momentum. For instance the SF company will hire pro bloggers, you work with an "influencer", etc.
