I have a mixture of all the the answers previously but the bottom line is the best growth strategy is to implement a growth process. As Sean Ellis said, "No individual growth hacker or even a growth team can outperform a company where everyone is mobilized to accelerate growth." One opinion and one action won't create growth, it is rather a mixture of first analyzing and testing EVERYTHING. Qualitative AND Quantitative questions.

You can take a free growth assessment here https://www.growthswell.com/#assessment To find out what level you are at and then it will tell you where you need to focus first based on your answers.

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!
