In my dissertation research I focused on determining the effectiveness of informational web sites on individual customer buying behavior. I show that this effectiveness, given the multichannel environment, is not necessarily positive and that customers have a lot to benefit from the information offered online.

behavior
– Channel = customer contact point or medium through which
the firm and the customer interact (Neslin et al., 2006).
– Multichannel customer behavior = customers’ choice and use
of multiple channels during the decision-making process.
– Multichannelling = firms reaching customers using a mix of
channel formats, (e.g., stores, web sites, direct mail and
kiosks) (Montoya-Weiss et al., 2003).
– Cross-channel effects = the effects of a change in behavior in
channel a on behavior in channel b.
5. Multichannel consumer behavior
Some effects on customer behavior
– Marketing efforts can migrate customers (Ansari et al.,
2006)
– Customer become multichannelers after the addition of
the Internet channel (Dholakia et al., 2005)
– Transactional Internet channel may increase or decrease
customer buying behavior (Kushwaha and Shankar, 2005;
Gensler et al., 2006)
Only 0.4% of 1300 studies published over a period of 7 years look
at informational web sites

7. Why informational web sites
• Informational sites educate or inform the consumer about
products or services offered by the company (e.g. Morton et
al., 2001).

• Web influenced 20% of in-store sales (Forrester Research,
2005).
• Web-to-store shoppers spend 70% more (Dieringer research
group, 2004).
• Consumers prefer offline buying given
– Type of product
– Situational influences
– Consumer anxieties
8. Research Questions

behavior?

23. Main findings
• For most customers, using the informational web site
decreases offline buying behavior
• For the minority of customers, using the informational site
increases offline buying behavior
• These customer:
– live closer to the store
– buy more items
– spent more money
– visit the store more often
– view more web pages
• Hence, seem to be the company’s ‘top customers’
24. Possible causes
• Efficient decision-making processes
– Use of an informational web site in a goal-directed
manner searching for the best alternative
• Reduced impulse buying
– Informational web sites do not allow transactions
increased processing resources decisions based on
cognition instead of impulse
• Reduced switching costs
– Competition click away, less psychological bonds
informational web site has disadvantage of not being able
to instantaneously buy the product
25. In conclusion
• The majority of customers spent less money!
– More online visits = less offline buying
• The company’s ‘top’ customers increase their spending
Limitations/future research
• The bottom line
• Competitors’ effects
• Other marketing instruments
• Empirical case study
Implementation of an informational web site should be
considered with great care!

28. Objective
• To gain insight into multichannel consumer behavior in an
informational web site / department store setting.
• Research questions:
– How do the components of online search and offline buying
behavior influence each other?
– How do marketing efforts influence both offline buying and online
search behavior?
– How do consumer characteristics influence multichannel
consumer behavior?
