The main purpose of Twitter is networking and making contacts, some of which might be interesting in your product, or they might be interested in telling their friends about your product. Create a Twitter page for you business... in the BIO- explain what the business is and what products you sell, and put your website URL in the website URL box. Create some tweets, but don't try to sell your products right away. Get some followers (searching or using tools like Twellow) and interact with them. Tweet content, not just "Buy my product". If you are interested in learning how to use Twitter for a business, then check out the book "The Tao of Twitter" by Mark Schaefer on Amazon. It is very helpful and a short, easy read. It will tell you how to effectively use Twitter!
