How to write the best killer Tweets?

Writing a killer tweet within a real estate of 140 characters is no less than copyrighting an advertisement for a newsletter. The only difference is that the newsletter is read only once, on a particular day while the tweet remains in the web almost for ever if not deleted otherwise. Another major difference is that you do not pay for your tweet and you can do it again and again and also delete your tweet at any time. So with this great amount of flexibility and this great tool in your hand, you have a chance to reach many people without even paying. But how your tweet pays off depends hugely on its content.
These 140 characters if used properly can become a killer marketing copy and create a havoc in the form of traffic to your website. To write a short sweet and really effective tweet we need to keep a few small things in mind. I will explain some of these things which will make your tweet an effective marketing message.
1. Decide what you want to communicate:- Just find out what you want to communicate to your followers and be sure about the marketing message you want to convey to your followers. Write down in brief the essense of your marketing message somewhere. For example the message you want to spread across is that you are giving a 20% discount on all your products to any of your followers who re-tweets and also shares the link of your site in his/her blog.
2. Write the tweet in around 80-100 characters and leave the remaining for the URL. Say for the above example I would write the Tweet in this way:- Hot Limited Period Offer - 20% Discount on products to all followers who tweet. To avail click here.
3 Use a URL shortening service to shorten the url size and use the twitter real estate to the fullest. Some of the examples of URL shortening service is http://bit.ly/ etc.

If you start writing tweets do not get too excited and tweet more than what is required. No one is a full time twitter and does not want too many tweets on their phone or account. If you are an individual, you should stick to one or two tweets a day to a maximum of 5 at different intervals. If you are an organization the maximum number of tweets you should not exceed in a day is 10. And remember these 10 tweets should not be all the same, or people will stop following you. If you want to tweet more, make sure you have the topics and things to tweet on. These limitations do not apply on organizations which are expected to send more frequent information to their followers like news broadcasters, sports broadcasters, etc.

So go ahead and write your first tweet which really makes an impact on your followers and makes them to take an action which you want them to.
