Twitter is a social networking, multilingual micro blogging tool that allows companies and businesses to keep in touch with their clients. Businesses can update their clients and prospective customers on new products, company news, and more through a 140 character "tweet." Clients who have a twitter.com membership (which is currently free) can choose to follow your business or your business can request to follow a client to stay in touch. As a social networking tool, Twitter's services have remarkable potential. However, if the service is not used correctly it can potentially harm your public image, create a perception that you did not intend, or hurt your business in terms of lost revenue. If you are looking to build a social network around your business, you must be ready to engage your network in various facets of your business: research and development, product design, and customer service are just a few key points. The idea is to have your network feel as though they have in some way contributed to the overall product or to the business in some way. Merely adding several people to follow does not aide your business in any way. The relationship you have with your network will determine the revenue you receive. If you have created a Twitter account for your business, leave the personal tweets about how you spent your Sunday and what you ate, out of the system. Granted some of you may have businesses you run as an individual, but the primary focus should always be the business you are promoting. If how you spent your Sunday has anything to do with the business focus or the business image you would like to impress upon your followers, then by all means tweet it! Try as much as possible to keep it professional. Your tweets should have an interpersonal touch; avoid the mechanical updates that a programmed robot would key. Treat your followers with care and keep them in the know of what's really going on with the business. Also, concerning your layout and background choice, I have seen several business profiles that lose it with their choice of backgrounds. If you have company colors and a logo, try and incorporate that into the layout design of your profile. One last yet terrible mistake for businesses using Twitter is always tweeting about themselves. As the name suggests it is a social tool which should be used to boost interaction between one's company and one's clients. A sure fire way of being avoided or ignored on Twitter is to constantly tweet about one's self and products only. Talk about, for example, a worthy cause that your business supported and add links to it.
