The title of Brent Dykes' book is a little misleading. Instead of being named, "Web Analytics Action Hero - Using Analysis to Gain Insight and Optimize Your Business," a much more apt title would be: "Web Analytics Novice - Your Introduction to Becoming an Action Hero." Despite what the title suggests, this is not really a how-to book.
Instead, Web Analytics Action Hero (Adobe Press; 2012) provides an overview of what a web analyst actually does. It explains how analysts might use analysis as part of their daily, weekly, or monthly work duties. However, most of the examples Dykes provides are for analysts who work in a large company or corporation. The examples don't really apply to small business owners or self-employed contractors.
One of the main focus points of this book is how an employee might get support for bringing analysis (as opposed to mere number-crunching and reporting) into the company. Dykes asks questions, both implicitly and explicitly, like, Who are your companies' stakeholders? What are their primary business objectives? How could you use analytics to meet these objectives and bring added value? Very important questions, indeed. But again, the focus is on how analytics can be used. Not on how to use analytics.
An exception might be the "Recognize Opportunities" subsection of Chapter 5 (pgs 107-116). In this section, Dykes provides some techniques for analyzing numerical data. For example, he briefly explains how to compare multiple related data sets and offers clear visual aids.
Some experienced analysts may also find Chapter 7 helpful. This chapter, "Analysis in Action," provides real-world examples of how one can pull data, such as traffic volume and conversion rates, from various analysis models and put it into different groupings. An experienced analyst should probably already be familiar with the tasks Dyke mentions in this chapter, but perhaps seeing visual representations of these tasks could help an analyst to think of how to group data in new ways.
While this book probably wouldn't provide much insight to a person already familiar with web analytics, I would definitely recommend this book to a person who is just beginning web analytics, or who is thinking about making a career change. I would also recommend this book to people who work in a field adjacent to web analytics, like advertising or web design.
All-in-all, though, if you consider yourself an experienced web analyst and you learn a lot from this book, then your career probably needs more help than this book can provide.
