"I'll never have to start from scratch again! In The Big Book of Key Performance Indicators, Eric Peterson has laid a solid foundation for any high-level web measurement project. This great reference gives me a head start at identifying just the most valuable metrics for my clients."

"I have all three of Eric's books but my favorites are Web Analytics Demystified and The Big Book of Key Performance Indicators. I love Web Analytics Demystified because it's an excellent primer for web analytics. I have used it with new analysts, marketing managers and even executives to get them to a basic understanding of why and how web analytics is an important business tool. The Big Book of KPIs is simply a great reference for valuable KPIs. Why struggle with figuring out which ones to use when it's already been done, very well, by Mr. Peterson?"

"When an e-commerce client became interested in developing a more sophisticated web analytics program, I needed to "brush up" and picked up a copy of Website Measurement Hacks. I finished it and immediately downloaded and read The Big Book of KPIs. These two books helped me to quickly prepare an actionable plan and clearly communicate the purpose and value to my client. They also made me realize how much I didn’t know that I didn’t know, and led me to purchase and read a copy of Web Analytics Demystified to continue to round out my ability to assist clients in the web analytics space. This suite of books has become my WA resource of choice because of its scope, depth, clarity, and obvious grounding in real world experience."

"Eric’s book, Web Analytics Demystified, helps approach your website with business-like thinking and methodology. Eric goes into detail about different implementations of web analytics, explains the big catch phrases such as “unique visitor”, “cost per conversion”, and “visitor segmentation” in plain English, and urges you to not only to measure but to continuously improve based on those measurements.

Our company has benefited from Eric’s books and his in-depth knowledge of web analytics and gems of marketing wisdom. Not only do our clients get more from web analytics than a monthly stats report, the insight we gain affects and improves every part of our business from sales to design to implementation and support. Instead of saying “We need to make this change to your shopping cart to sell more!” and hoping everyone involved jumps on board, we now say “We think this change would improve conversion rates, here are the website data and analysis we are basing this recommendation on and we can measure the visitor response to these changes.”

Web Analytics is growing more popular by the day. Read Eric Peterson’s book – Web Analytics Demystified – and get your website doing more for your business."

"The Big Book of Key Performance Indicators (KPI) is a practical, compact guide for everybody that wants to know if their website its successful. How to measure that? By seeing the percentage of the KPI drop or raise! Eric T Peterson explains the numbers, and whom in your organisation should get the reports on these number, and important, who you have to contact when great changes appear. An already prepared Excel file is delivered with it.. how practical! You just gained knowledge, which you can practice right away. And remember always: KPI’s are RELATIVE not ABSOLUT! A must-read for communications professionals that want to know the real important numbers in webanalytics. But be aware, some knowledge of the most common terms in webanalytics is needed to fully understand this book."

"I have Eric's three books and found them all practically useful. Web Analytics Demystified are good for wide range of readers while Web Site Measurement Hacks is more comprehensive. I bought more than 10 copies to give my young staff to study about web analytics. The Big Book of Key Performance Indicators is written on the difficult subject but in an easily understood manner. Because I want to share Eric's talent beyond English speakers, we decided to make the Japanese translation of the latter two books.”

"Eric T. Peterson's web analytics writings are essential reading for anyone involved with web metrics. I use The Big Book of Key Performance Indicators for engagement and loyalty metrics at IBM and for my own SEO/SEM clients. If you buy any books to learn or deepen your understanding of what web analytics is, and what it can measure, buy Eric T. Peterson's three books -- Web Analytics Demystified, Web Site Measurement Hacks and The Big Book of Key Performance Indicators -- you won't be sorry!"
