Advanced Web Metrics is an outstanding book. It covers from shallow to Deep Ocean and gives the necessary tools to navigate through waves, tempests and calm seas. And it shows the reader how to find islands of insights!
Brian Clifton describes techniques that will help you understand and improve your website using Google Analytics. He goes over very important concepts and questions that are usually misunderstood: Why Web Analytics is important & what are the available technologies? How Google Analytics works & how it deals with privacy? Which reports should you use & how to do it? How to ensure that your data is accurate & how to enhance your reports using advanced implementation techniques?
The book is not a theoretical read; it goes into real world tasks and shows the reader what he needs to know in order to succeed using Google Analytics. In addition to showing all there is to be shown on Google Analytics, he also provides some very useful examples on third party applications that use the Google Analytics API and out of the box integrations with other tools or sources of data (CRM, call tracking, Website Optimizer).
But the biggest quality of this book is the way Dr. Clifton approaches the subject. Even readers acquainted with Google Analytics and optimization techniques described in the book will find insights that will help them understand the subject deeper and organize the knowledge in their brains.
