Since you mentioned that these social media profiles are for your business, I assume that you're going to use them to represent your company. If that's the case, then you should create a page that would really help you engage with the people who happen to encounter it. Another thing that you have to remember is that you're representing a bigger entity here. It's not about you; it's about your business. Keep that in mind, and you'll know how to properly use the social media accounts for your business. If you're looking for a software that can help you out, check TweetDeck and Hootsuite.
