- 5. What is Word of Mouth?
“Personal or non-personal communication, between
a non-commercial communicator and a receiver
concerning a brand, a product, or a service offered
for sale.”
Can entail ‘digital WOM’ (Alon et al. 2002; Bickart
and Schindler 2002; Newman 1999; Stokes and
Lomax 2002).

- 6. The importance of WOM – Geography
WOM is a global phenomenon (Money 2000; Takada and Jain
1991; Watkins and Liu 1996). WOM has been found to be of
importance in:
Western countries, such as:
the UK (Ranaweera and Prabhu 2003; Stokes and
Lomax 2002)
the US (Brown et al. 2005; Whyte 1954)
Canada (Bansal and Voyer 2000)

- 7. The importance of WOM
– Product categories (1)
WOM’s applicability appears to be universal
WOM’s importance stretches across a multitude of
product categories
However, certain types of products are more
susceptible to WOM than others:
Services in general
Professional services in particular

- 12. The importance of WOM
– Many are talking…
Word-of-mouth (WOM) is ever present
90% of Innovators had talked to at least one person a few days
after product trial (Engel et al. 1969)
More than 80% of diners talked about the food during consumption
(Bone 1992)
70% of consumers had engaged in WOM after product
consumption (i.e. watching a movie) (Bayus et al. 1985)
More than 50% of consumers engage in WOM (Anderson 1998).
Those who do talk to an average of:
9.5 people (Sweden) and
7.9 people (US)
© Bodo Lang bodo.lang@manukau.ac.nz 10
- 13. The importance of WOM – … and many
are listening
Generally, between 9% and 75% rely on WOM (Barnes 1986; East
et al. 2005)
The proportion of consumers who rely on WOM as the main source
of information can vary from 9% to 65% (East et al. 2005)
Approximately 50% of all Americans rely on WOM prior to buying a
product or a service (Walker 1995)
Around 60% of consumers who had tried an automotive diagnostic
centre named WOM as the most influential source in making this
decision (Engel et al. 1969; Engel et al. 1969)
Around 65% of residents in a community relied on WOM to find a
physician (Feldman and Spencer 1965)
75% of patients chose a dentist through WOM (Barnes 1986)

- 14. The importance of WOM – Its relative
strength
WOM is more powerful than:
Print or television advertising (Beal and Rogers 1957; Buttle
1998; East et al. 2005; Hinde 1999; Katz and Lazarsfeld
1955; Traylor and Mathias 1983)
Independent third-party reviews (e.g. Consumer reports or
published restaurant reviews) (Herr et al. 1991; Hinde 1999;
Price and Feick 1984)
Consumers’ own attitudes (Bourne 1957).
WOM has also been found to be a more dominant
source of information than a consumer’s own information
search, sales staff and other factors (East et al. 2005)
© Bodo Lang bodo.lang@manukau.ac.nz 12
- 15. WOM – Asset or Liability?
WOM can range from highly positive to highly negative (Bolen
1994; Derbaix and Vanhamme 2003; Donavan et al. 1999;
Mangold et al. 1999)
This is a KEY difference between WOM and other marketing
channels.
Positive WOM seems prevalent in both traditional WOM (Bayus et
al. 1985; East et al. 2005) and digital WOM (Dellarocas 2003)
Relative impact of positive and negative WOM has been found to
be quite similar (East et al. 2005)
© Bodo Lang bodo.lang@manukau.ac.nz 13
- 16. WOM – Asset or Liability? (2)
Some negative WOM may be inevitable
So how much risk is your brand exposed to?
“Different conditions may be associated with the utterance of
negative and positive word of mouth.” (Buttle, 1998, p. 248)
The following is a pragmatic approach to determine whether your
brand has:
a lot to gain (i.e. WOM may be an asset) or
a lot to lose (i.e. WOM may be a liability)
Answering four questions may yield the answer
Develop a WOM asset/liability score
© Bodo Lang bodo.lang@manukau.ac.nz 14
- 17. WOM – Asset or Liability? – Q1
Customer satisfaction
How satisfied are your customers?
Dissatisfied Satisfied Highly satisfied
-1 0 +1
Customer satisfaction is said to have a non-linear relationship with
WOM (Anderson 1998; Bowman and Narayandas 2001; Derbaix and
Vanhamme 2003; Engel et al. 1969; Soderlund 1998)
My research shows that “Very satisfied” retail bank customers are
more than 6 times more likely to recommend their bank to someone
else, compared to customers who are simply “Satisfied” (82% versus
13%)
Thus, high levels of customer satisfaction are likely to lead to a much
lower propensity to share negative WOM and a much greater
propensity to share positive WOM
© Bodo Lang bodo.lang@manukau.ac.nz 15
- 18. WOM – Asset or Liability? – Q2
Customer co-production
How involved are your customers in product design/delivery?
Not at all Somewhat Highly
-1 0 +1
Customers who engage in the co-production of a service have a
desire to portray ‘their’ organisation as positively as possible
(Brown et al. 2005; Gilly and Wolfinbarger 1998). Such customers
may “talk up” a company as a defense mechanism (Brown et al.
2005)
Thus, high levels of co-production are likely to lead to a lower
propensity to share negative WOM and a greater propensity to
share positive WOM
© Bodo Lang bodo.lang@manukau.ac.nz 16
- 19. WOM – Asset or Liability? – Q3
Industry concentration
How many competitors can your customers chose from?
None/Very few Some Many
-1 0 +1
The level of industry concentration in an industry (e.g. many
suppliers versus only one supplier) is inversely related to voice
behaviour (Fornell and Didow 1980; Singh 1990).
Thus, low levels of industry concentration (i.e. many competitors)
are likely to lead to a lower propensity to share negative WOM and
a greater propensity to share positive WOM
© Bodo Lang bodo.lang@manukau.ac.nz 17
- 20. WOM – Asset or Liability? – Q4
Self-relatedness
How much is your brand related to your customers ‘self’?
Not at all Somewhat Very much
-1 0 +1
Brands that are more self-related to consumers self-concept foster
higher levels of WOM in general and greater positive WOM in
particular (Chung 2000)
Thus, high levels of self-relatedness are likely to lead to a lower
propensity to share negative WOM and a greater propensity to
share positive WOM

- 21. How exposed are you to WOM?
Answering the 4 questions:

1. Customer satisfaction Dissatisfied Satisfied Very satisfied
2. Co-production Not at all Somewhat Very much
3. Number of suppliers None/Very few Some Many
4. Self-relatedness Not at all Somewhat Very much

- 23. Summary & Discussion (1)
WOM is VERY important
WOM is “[…] capable of catapulting products from obscurity
into runaway commercial successes” (Dye 2000, p.139).
Acclaimed business writers have suggested that WOM is the
only marketing outcome variable that managers should be
concerned about (Reichheld 2003)
While harnessing the power of positive WOM is a pleasing thought,
- don’t forget about preventing/managing negative WOM
By answering 4 questions we have seen how WOM can either be
an asset or a liability for a brand
Customer satisfaction
Level of co-production
Number of suppliers
Self-relatedness
Total WOM asset/liability score
Ranges from -4 to +4
© Bodo Lang bodo.lang@manukau.ac.nz 21
- 24. Summary & Discussion (2)
Brands that have a high WOM asset/liability score, will reap huge
benefits. Such brands should endeavour to capitalise on WOM
through innovative use of marketing techniques, e.g. viral
marketing, guerrilla marketing, etc.
Conversely, brands with a low WOM asset/liability score are in
serious danger of going out of business. While not all brands may
care about this, for example utility monopolies, negative WOM may
also alert other firms of vulnerable take-over targets.
Furthermore, such brands may also need to spend significantly
more on other marketing communication to combat the detrimental
effects of WOM. Thus, a low WOM asset/liability score has a
number of disadvantages
Your brand’s WOM asset/liability score works at two levels:
absolute and relative to the competition. The latter is more insightful
in most cases
