At the very least, set up your profile on the biggest social networks, that are relevant to your audience. Have professional pictures done of yourself. Create a consistent backdrop across all of them. Have a look at mine as an example. Share about posts that are related to your products/services or curated articles around your products. You want to be human, show a little of yourself so that people can fall in love with you persona. I've built a following of over 24K on all the networks I am active on over the past 9 years. As a growth hacker, of course I will tell you to set up tests so that you can measure what works for your audience and what doesn't. You learn by testing and observing. Good luck!
