Effective microblogging messages emphasize clarity and conciseness and so do effective sales messages.

Your task: 

Find the website of any product that can be ordered online (any product you find interesting and that is appropriate to use for a class assignment). Adapt the information on the website, using your own words, and write four tweets to promote the product. The first should get your audience’s attention (with an intriguing benefit claim, for example), the second should build audience interest by providing some support for the claim you made in the first message, the third should increase readers’ desire to have the product by layering on one or two more buyer benefits, and the fourth should motivate readers to take action to place an order. Your first three tweets can be up to 140 characters, but the fourth should be limited to 117 to accommodate a URL (you don’t need to include the URL in your message, however). 

If your class is set up with private Twitter accounts, use them to share your messages. Otherwise, email your four messages to your instructor or post them on your class blog, as your instructor directs.
