DESCRIPTION

This deck describes how people actually buy brands based on an analysis of several million purchase events over a period of 5 years across three different categories in the United Kingdom. It was presented at the ESOMAR Congress 2012 conference in Atlanta, USA in September 2012. I'm particularly proud of the illustrations in the presentation... although the fundamental nature of the research is pretty cool too :)

The Chaos Beneath the Surface

Buying behaviour is surprisingly complexSurvey-derived UK laundry dual usage network demonstrating the amount of movement between brands beneath the surface. There is much more inter-brand usage than many marketers expect.

How to read: node size represents brand penetration (% users in past 12 months); thickness of connecting lines represents % dual users of the two brands in past 12 months

What about other categories?Source: Coyles, S & Gokey, TC. 2002. Customer Retention is Not Enough, The McKinsey Quarterly 2002 No.2What Does It All Mean?

Measures must correlate at an aggregate AND respondent level

Markets are dynamic. Most people will change their spend over time

Many customers are transient

Brands lose and gain fractions of a person, not a whole person.

Strong memory structures are created (and activated) through sophisticated mass marketing and brand building
