Which social media platforms should my brand be present on?

First things first, there’s no doubt that your business should be on social media, regardless of the industry. The purpose behind having a social media presence, however, may differ from one company to another. As a brand, you need to know where your audience is and start from there.
With that out of the way, the bare minimum includes an account on Facebook, Twitter and Linkedin. The first two are meant for more light-hearted B2C updates, while the latter is mostly used for HR initiatives and B2B relationships. From here on, you can expand to Instagram, Snapchat, Pinterest, Google+, or others, depending on who you want to approach and with what purpose.
