In order to design better search experiences, we need to understand the complexities of human information-seeking behaviour. In this paper, we propose a model of information behavior based on the needs of users of consumer-oriented websites and search applications. The model consists of a set of search modes that that users employ to satisfy their information search and discovery goals. We present design suggestions for how each of these modes can be supported in existing interactive systems, focusing in particular on those that have been supported in interesting or novel ways.

5.  Information needs gathered thru client
engagements (stakeholder workshops), e.g.
▪ “Find best offers before the others do so I can have a high margin”
▪ “Get help and guidance on how to sell my car safely so that I can
achieve a good price”

18. From research to practice
• We all want our work to have impact -
• We need to close the gap from both sides
A Model of Consumer Search Behaviour
• Design examples illustrate scope and boundaries
• Minimise the conceptual gap and drive adoption
