I\u2019m a firm believer that everyone should have their own business or sideline business, as well as passive revenue.\u00a0 Online businesses offer the opportunity for both. That\u2019s why I was excited to receive a review copy of, "KaChing:\u00a0 How to Run an Online Business that Pays and Pays," by well-known entrepreneur and author, Joel Comm (Wiley, 2010). Since I already make a portion of my revenues from my online businesses, I consider myself at least intermediate in my knowledge of online marketing and how to create online revenue streams. I wasn\u2019t sure if I\u2019d really learn anything from this book, but I figured I\u2019d at least enjoy it. Online Business Tips I like how Comm set up the structure of the book.\u00a0 He starts by giving an overview, then explains the importance of niches (this concept can never be hammered home enough, in my un-humble opinion), before stating the primary ways to make money online. He also shares his seven keys to online success, and gives examples: You Have to Dream You Have to Believe You Have to Prepare You Have to Act You Have to Relate You Have to Use Models You Have to Grow Ways to Make Money Online Comm shares with the reader the primary ways to make money online: blogging and other online content, information products, affiliate programs, membership sites and coaching programs. Case studies and specific examples, as well as resources to make the process easier, help explain the sometimes tricky world of online business. And if you\u2019re someone who enjoys a book that contains how-to information, you won\u2019t be disappointed.\u00a0 Comm is not only a strategist, but he created a well-known iPhone app. In this book he explains\u00a0 a concept such as using Google AdSense ads to make money online, as well as some of the coding techniques to make it more effective. The verdict: If you are a beginner, you\u2019ll definitely learn some great ways, as well as important models, to make money online.\u00a0 If you are already making money online, you\u2019ll probably gain a few useful nuggets to help you achieve even more success.
