Most books either address the broad concepts of web analytics or provide a long list of tips & tricks for a specific product. This is not the case with Brian's book. It's the first one I see that brings the concepts and apply them to a specific tool, namely Google Analytics.
Simply put, anyone starting in the field should have three books on their shelf:
- "Web Analytics an hour a day" from Avinash Kaushik
- "Advanced web metrics with Google Analytics" by Brian Clifton
- "Always be testing" by Bryan Eisenberg.
Don't just take my word for it, read others reviews and why a Brian wanted to publish a second edition.
