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. Conveying messages to the wrong crowd will end up in a lot of dissatisfaction for all involved parties.
Bear in mind that some channels are focused on B2B, while others take a B2C approach. The decision depends on the product or service that you’re providing, as well as on your audience.
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.
