Twitter can be a great tool for reaching out and marketing to folks online. It's relatively easy to gain a large following in a short space of time. Also very easy to connect and share content with others within your niche. And there's also a pretty good chance that if you post the right content, it will go viral and gain you plenty more followers and goodwill. The downside with using Twitter is that there is a massive churn out rate. You can count on the fact that at least 30 percent of your followers will not be active. Another problem is that plenty of your followers will unfollow you sometime down the line, for whatever reason. It's a challenge to maintain a truly loyal following over a long period of time. Cleverly worded tweets, hashtags and targeted ad campaigns on Twitter do work. However, mileage does vary and these only drive traffic to your offer for a brief amount of time. That's why it's important to tweet often but that can also annoy some of your followers who will undoubtedly unfollow you. So a word of caution when proceeding with any form of marketing on Twitter.
