Businesses can use Twitter as a marketing tool in a variety of ways. Many business owners struggle with social media as a marketing medium. At the heart of the most effective social media marketing campaigns is personal communication. Many businesses that try to manage social media may attempt to shout their message, rather than simply engaging with potential customers. Potential customers who are active in social networks will not be receptive to marketing in this fashion. The trick with social media like Twitter is to interact and engage, rather than shouting your message.
