Advanced Web Metrics with Google Analytics
A compilation of great GA Hacks
Brian Clifton has done an excellent job putting together several very useful hacks for Google Analytics. And even though this already gives you a reason to read his book (if you use Google Analytics and feel that you could be getting out more of it), he also manages to write some fine chapter on the importance of web analytics to the online business process.
The book is well written and balances technical contents with other more gentle insights in the line of Avinash’s Web Analytics an Hour a Day.
