Social media is everywhere. The overwhelming majority of people, or their businesses have multiple social media accounts.
For any business on social media, it’s important to keep interactions going. You should be social on social. That doesn’t mean you can’t post formal statements, or simple links in a short to-the-point message. It means that you need to reply in a social context, and be human with any further interactions. No-one wants to be treated as a number or a future pay cheque.
Always interact in a warm social way.
