Making the decision to get started with Twitter is a big decision because you will need to make a commitment to the process.
You must demonstrate to your customers, clients and potential customers and clients that you are reliable and provide worthwhile information.
Here are three decisions to make before you even get started.
However if you have already started you can make changes if necessary too...

1. Do your research - take a look at what other successful people are using Twitter for.
   Check out their conversations, analyze how their activities will fit into your marketing plan.
   Decide what you want your main message to be.
   Consistency is important, if people come to you for Social Media Marketing advice tweeting about how to take care of a hamster will confuse them.
   AND have them wondering who you are and what you are all about.
   
2. Know your goals - Twitter is being used for many different purposes today.
   You can use it to send interested people over to your website where they can purchase a product or service, for customer service, for initiating relationships or for creating demand for your customer loyalty program.
   Any purpose is good, it simply depends upon the goals and needs of YOUR business.
   
3. Decide on your profile - there are basically three choices for your profile.
   A) personal profile where you use your name, I strongly recommend that even if you chose not to go with a personal profile that you register for your name.
   That way in the future if you decide to switch to your name won't be taken by another of the same name.
   B) branded profile with your company name or C) a combination of both.
   

Go out and take a look, find profiles that appeal to you.
Check out how they tweet and what they tweet about.
With that information you will be much better prepared for making your own account a success.
