Twitter is not just about communication it is about online sales

Twitter can be used as a good marketing tool. Although, Twitter grew 131 percent in March 2009, reports .comScore, the studies showed that a lot of people visit Twitter a few times and never come back. Mainly this is because the site fails in fulfilling its purpose. Twitter is designed to be a conversational tool. However, it is difficult to have conversations when you just join, and don't have any followers.

However, Twitter can still be used as a phenomenal marketing tool for salespeople. The service provides an opportunity to market goods or services to your followers. Salespeople can and should be using Twitter to attract additional customers, and carry out ongoing communication with current ones. 

However, users of the site have to be cautious of proper and improper ways of using Twitter and follow Twitter etiquette, as there is a risk of being blocked or banned.
