This is the question that I get asked the most. While there is no one solution that fits all because once you are choosing a platform between hundreds of different social media possibilities, you have to consider two things.
First, what is the goal of your personal branding and secondly, who is your target audience? And what platform are they using?
Every social media platform has its advantages and disadvantages and each platform has its own philosophy, format and rules of the game. However, all of them have one thing in common-other people on another side of the screen, so irrespective of what platform you choose, building relations with your audience, staying human and authentic as well consistently being present is the key.
It is also important to have a clear strategy in place and understand, whether the selected platform is serving as your passive virtual business card or an active communication platform. You don’t have to be on every possible platform 24/7 to achieve your goals. You just need to be there, where your customers are and build your circle of influence strategically.
I would say if you are a professional in B2B, most probably the best possible channel to concentrate on is here on LinkedIn. Once you have one channel working well, you can add other channels into the mix, if this would add additional value.
