Use your personal picture
Seeing a face instead of a company logo will immediately build rapport with your followers. Engage with your customers online as if you were conducting business with them in person.
Join the conversation
It's about interacting. Don't just promote yourself. Write about something that is of interest to your audience. Pass along information. If someone posts an interesting tweet, be sure to "retweet" that person. You're building a professional relationship. This leads us to:
Find out what your customers want
Engage your followers and potential clients to find out what really interests them. You may discover new ways to provide a unique local service and customer experience.
Tweet often
It doesn't take much time. Just a single sentence. If you see an article on the Web that you think would interest others, send it. Your followers will start to grow!
Add your Twitter URL to your business cards
Invite people into your discussions by providing a URL for people to find and follow you. Give potential clients and customers choices for ways they would like to communicate with you.
Proofread your tweets
Make sure your tweets are grammatical, spelled correctly and make sense in 140 characters. They are a reflection of you.
