Kamel: Focus on measuring the minimum you absolutely must to drive the maximum relevant impact. That sounds like a simple principle, but it's in stark contrast to what people have done for the past 15 years, where there has been a tendency to measure everything that's measurable just in case you might need it. Focus on collecting outcomes that matter, which are aligned with and enable the achievement of your visitors' objectives as well as your business goals. If you can do that with fewer amounts of data, good on you. It's not about quantity, it's about quality.
Harris: We focus in the book on the need to develop more proprietary and unique metrics to focus not only on what happened in the past, but on what ought to happen next.
Kamel: Web metrics have been around a long time, and I think we're at an inflection point in the industry where there is a new direction emerging.
People are saying, “Wait a minute, what we've been doing all this time may not be the best way for us [going] forward.” One of the emergent practices that I think is showing real promise is to discern, hopefully at the point of entry, what the visitor's purpose is and how can I dynamically optimize the experience to fit that purpose.
