When this book was released in March, I already owned Brian's two previous editions, so I was a little on the fence about buying the third edition. Eventually, I broke down and bought the 3rd edition, because my second edition was so worn-out. To my surprise the 3rd edition was much larger than the 2nd edition, so I quickly saw this was not just a re-hash of the same. Not only was this book chock full of new information, it had some great code examples for the new version of Google Analytics. This is what I expect in a book titled "Advanced Web Metrics." I can get the basics online, in blogs, but Brian's books really help as a guide to going to the next level. Don't get me wrong there is a good balance here, with plently for those new to Google Analytics as well, including a lovely "Google Analytics in Color" section for those unfamiliar with GA. In short, this book I keep handy as my reference for the right answer on most questions and I cannot recommend it enough for those who are serious about analytics. It was worth every penny.
