This book is both informative and fun. Howie Jacobson obviously knows Google AdWords inside and out. The layout is logical and the text easy to understand. It is a must have if you want to unleash the potential of Google AdWords to help your business in the world of eCommerce. If there is something about Google AdWords that you think is unclear or mysterious then this book removes the "mirrors and smoke". I wanted to give it six stars but that wasn't an option. So five stars plus is my rating!
