Setting up a Twitter account for business purposes requires choosing between a personal or company account. A company account represents the business as a whole and is used to promote events, blog posts, products/services, and provide real-time updates. A personal account allows an individual employee to act as a liaison, share what they're working on, and expand their network. The username, or "handle", is important as it will be how people identify you; it should be as close to your real name as possible for authenticity and recognition. Key details like your profile and bio then need to be optimized to introduce your business.
