If you are knowledgeable about Google, you get a lot of questions about how it works. Wouldn't it be nice to be able to say: "Here, read this, and you'll have all you need to get started."
Dave Taylor's Growing Your Business with Google is just the book to have lying around if you work with people who need to get up to speed on Google and the internet marketing world. It covers how Google works - including search results, AdWords and AdSense, and is easy to read since the book has a lot of side bars and tips that can be quickly scanned.
So, hand out a few copies of this book, and you'll save yourself a lot of time.
