A"stract
Word-of-mouth communication (WOM) is a dominant force in the marketplace for services.
However, the current body of research provides little insiht into the nature of WOM in the
service marketplace. !eports the results of a content-analytic study that provides insiht into
WOM"s content and the catalysts by which it is stimulated. #he oal was to capture a series of
$rounded events% from which broader patterns could be discerned. #hese rounded events
were actual incidents of WOM as described by the recipients of a communication. #hree
content cateories and ten catalyst cateories are identified. &mplications for manaers areaddressed.

!esearch indicates that word-of-mouth communication (WOM) has a sinificant effect on
consumer purchasin behavior. One study conducted by the + Office of 'onsumer ffairs
indicated that, on averae, one dissatisfied customer can be e?pected to tell nine other people
about the e?periences that resulted in the dissatisfaction. atisfied customers, on the other
hand, relate their story to an averae of five other people (2nauer, 466@). uch
communication e?erts a stron influence on consumer purchasin behavior, influencin both
short-term and lon-term Audments (9one, 466> 9urBynski and 9ayer, 4677 Herret al.,
4664). #his influence appears to be particularly sinificant when the communication is
consistent with the individual"s feelins toward the product under consideration (Wilson and
:eterson, 4686).
WOM seems particularly important to the marketin of services. 'onsumers have been found
to rely on WOM to reduce the level of perceived risk and the uncertainty that are often
associated with service purchase decisions (Murray, 4664). 'ompared to purchasers of oods,
Murray (4664) found that service purchasers have reater confidence in personal sources of
information as well as a reater prepurchase preference for personal information sources. He
also found that personal sources have a reater influence on purchasers of services than on
purchasers of products.
#he purpose of this research is to provide insiht into the nature of WOM as it relates to the
service marketplace. What situational circumstances and motivations stimulate WOMC /or
e?ample, is WOM freDuently stimulated by hih levels of satisfaction or dissatisfaction withprevious service encountersC 'an eneraliBations be drawn about the content of WOMC /or
e?ample, is the price of the service freDuently discussed amon WOM participantsC
+onceptual "ackground
substantial body of research indicates that interpersonal communication has a sinificant
impact on consumer purchasin behavior. 0arly studies attributed this impact to normative
social influence (sch, 46>5 tafford, 46

ne?t, provides further rationale for the sinificant influence that WOM is believed to have on
purchasin behavior.
Accessibility"diagnosticity model
ccordin to the accessibility-dianosticity model, the influence of a particular piece ofinformation will depend on the accessibility (from memory) of that piece of information, the
accessibility of alternative pieces of information, the dianosticity of the piece of information,
and the dianosticity of the alternative pieces of information (/eldman and ynch, 4688
ynchet al., 4688). Eianosticity refers to the deree to which information helps consumers
to cateoriBe products (i.e. hih Duality vs. low Duality).
!esearch conducted by Herr et al.(4664) supports the idea that WOM is accessible. #hey
found that WOM had a reater impact on product Audments than printed information.
/avorable brand attitudes were formed on the basis of a sinle, favorable WOM
communication, even when e?tensive, dianostic attribute information was also available. #he
authors suest that the impact of WOM on product Audments is attributable to its vividness,as opposed to pallidness, as a form of communication. 1ividness refers to the deree to which
information is $(a) emotionally interestin, (b) concrete and imaery-provokin, and (c)
pro?imate in a sensory, temporal, or spatial way% (isbett and !oss, 468;, p. =>). 1ivid
communication media are believed to attract attention to the information, hold attention, and
increase the information"s accessibility from memory and its impact on consumer Audment
(Herret al., 4664 isbett and !oss, 468;).
WOM can be considered to be dianostic in nature $to the deree that consumers believe that
the decision implied by that input alone would accomplish their decision oals (e.. ma?imiBe
utility, choose a Austifiable alternative, and so on)% (ynchet al., 4688). #his suests that
WOM may be more dianostic in nature than nonpersonal sources of information such as
media advertisin. #he effects of WOM appear to be reduced, however, when more
dianostic pieces of information, such as prior impressions, are available or when e?tremely
neative attribute information is available (Herret al., 4664). Other factors that underlie
WOM are discussed ne?t.
Underlying factors
0vidence indicates that WOM is often related to consumers" satisfaction or dissatisfaction
with previous purchasin e?periences (9lodettet al., 4665 9rown and 9eltramini, 4686
!ichins, 4685 Wilson and :eterson, 4686). 'onsumers also appear to enae in WOM tosatisfy their personal information needs (9lochet al., 468

consumers who blame the dissatisfaction on the marketin institutions, rather than themselves
or their own behavior, were more likely to enae in neative WOM.
#hese findins are consistent with 9lodettet al.(4665) who indicated that consumers"
tendency to enae in neative WOM was larely dependent on their perception of Austice as
it related to the complaint. #hat is, consumers were less likely to enae in neative WOM ifthey felt that the procedures for complainin and the provider"s response (i.e. outcome) were
fair and if they had positive feelins about the manner in which they were treated. Other
factors that appear to be correlated with consumers" tendency to enae in neative WOM
include the level of inconvenience that resulted from the problem, the e?tent to which the
customer perceived that the problem was under manaement"s control, and manaement"s
perceived responsiveness to the customer"s problem (9rown and 9eltramini, 4686).
#he e?ploratory research described ne?t provides additional insiht into WOM"s content and
the human motivations and situational circumstances that stimulate WOM.
Methodology
#he oal of this research was to capture a series of $rounded events% from which broader
patterns could be discerned (Eeshpande, 4685 3laser and trauss, 46) in her study of customer switchin behavior. Fuestionnaires were distributed to 44@
Aunior and senior-level underraduate students enrolled in a collee of business at a university
located in the outheastern portion of the +. 0ach student was asked to complete one
Duestionnaire based on their own WOM e?periences. #hey were also asked to distribute
Duestionnaires to two acDuaintances who were over the ae of @> and reDuest that they
complete them. dditional Duestionnaires were distributed to a roup of ten raduate students,
all of whom were workin full-time and enrolled in an off-campus niht class at the same
university. 0ach raduate student was asked to complete one Duestionnaire and distribute four
other Duestionnaires to acDuaintances who were over the ae of @>. #hus, thouh students
were used to collect the sample, only @6 percent of the resultin pool of respondents were
students.
!espondents were first asked to indicate which of 77 services they had purchased durin the
previous si?-month period. #he 77 services listed were drawn from the Standard Industrial
ClassificationManual(Office of Manaement and 9udet, 4687). #he purpose of this
Duestion was to stimulate subAects" thinkin and help subAects to focus on a limited array of
services.
#he si?-month time frame was selected to provide adeDuate time for respondents to have
made multiple service purchases. Get, respondents were able to remember the details of the
communication surroundin the purchase. #he si?-month time frame is consistent with 9itner
et al. (466=) who asked respondents to report events from the recent past and defined thattime period as si? to 4@ months.

!espondents were then asked to think about the last time someone told them somethin
positive about a service that they may have had an interest in purchasin. #hen, they were
asked to think about the last time someone told them somethin neative about a service that
they may have had an interest in purchasin. #hus, each respondent reported on two WOM
communication incidents, one positive and the other neative. &n reard to each event,
respondents were asked (i) what service they were thinkin about, (ii) how lon ao thecommunication had occurred, (iii) what was said, (iv) respondents" relationship with the
person to whom they were speakin, (v) how the particular WOM came about, (vi) whether
the WOM was part of a broader conversation and, if so, (vii) how that broader conversation
came about. Open-ended response formats were used for each Duestion. skin for the most
recent observation in each communication cateory (positive and neative) prevented
respondents from describin only the most emotion-laden events. !espondents were also
more likely to have an accurate recollection of the most recent event.
#he interity of the data was insured throuh the use of follow-up telephone interviews. One
respondent was chosen arbitrarily from each set of three (five for the M9 students) and
contacted by telephone to verify that they had personally answered the Duestionnaire. detailed e?amination of the Duestionnaires was undertaken when telephone contact could not
be established after several tries. #hese Duestionnaires had to meet three criteria to remain in
the sample
the handwritin had to be different for each Duestionnaire, indicatin that the student
had not fabricated the other responses
the communication had to convey full and precise details, another indicator of
authenticity and
the communication had to have face validity (i.e. seem reasonable).
#he stimulants of WOM were e?amined throuh the use of critical incident techniDue. 'ritical
incident techniDue is a content analytic research method that enables researchers to classify
open-ended research responses into meaninful cateories, thereby reducin broad-based
answers into more relevant, manaeable bits of information (Weber, 468>, p. >). /or the
purposes of our research, critical incidents were defined as any event or events that led the
subAect to communicate via the spoken word, either positively or neatively, reardin a iven
service.
'ontent analysis was also used to e?amine the substance of the WOM itself. &n this case, the
analysis focused on the substance of the communication rather than the critical incidents that
led to the communication.
+ategory development, assessment of sample si/e, and assessment of content validity
and relia"ility
#he data collection process resulted in a total of =;@ critical incidents. ome of these
responses were unusable and were, therefore, eliminated from the study. everal of the
responses were eliminated because the respondents had inadvertently based their answers on
communication that related to a product rather than a service. ome were eliminated because
the individual with whom the communication occurred was a salesperson or other employee
who was workin for the provider of the service. Other responses were discarded because the
answers were Auded to be too vaue while still others were discarded as a result of thesample validation procedure described previously. fter the elimination of the unusable

responses, 545 responses remained for the e?amination of WOM"s contents. 9ecause 46 of
the usable responses did not contain stimulus-related information, @6= responses remained for
the e?amination of WOM"s stimulants.
#he critical incidents were subdivided into a classification sample and a holdout sample
consistin of 4;; responses. #he classification sample consisted of 46= cases for the testin ofWOM"s stimulants and @45 cases for the testin of its contents. #he identification and
classification of stimulants was based primarily on the open-ended Duestion in which
respondents were asked to $Iplease indicate, as specifically as possible, how this particular
word-of-mouth communication came about (i.e. what stimulated the conversation).% #he
identification and classification of contents were based primarily on the Duestion, $:lease
indicate, as precisely as possible, what you were told.%
#he analysis of WOM"s stimulants resulted in the identification of ten mutually e?clusive and
e?haustive cateories from the classification sample. (While the cateories were mutually
e?clusive and e?haustive, some responses contained elements of two or more cateories. &n
these cases, the researcher"s task was to determine the primary stimulus.) #he incidents in theholdout sample were then added to the analysis. o additional cateories emered as a result
of the addition of these 4;; incidents.
#he analysis of WOM"s contents resulted in the identification of three mutually e?clusive and
e?haustive cateories from the classification sample (#able &&). ain, no additional
cateories emered when the 4;; cases in the holdout sample were added to the data set.
#hese results indicate that the sample siBe was adeDuate for the testin of both WOM"s
stimulants and its contents. ccordin to /lanaan (46>=, p. 5=5), $/or most purposes, it can
be considered that adeDuate coverae has been achieved when the addition of 4;; critical
incidents to the sample adds only two or three critical behaviors.% #he emerence of no
additional cateories after the addition of 4;; new cases also provides stron evidence of
satisfactory content validity (/lanaan, 46>= 2eaveney, 466> !onan and atham, 467=).
second Aude was asked to sort the incidents into the cateories and subcateories provided
by the first Aude and to create new cateories, if appropriate. #he level of initial interAude
areement under this procedure was 8> percent for WOM"s stimulants and 6= percent for its
content. While there is no accepted standard for evaluatin the reliability of such nominally
coded data (:erreault and eih, 4686), similar levels of areement have enerally been
considered an indication of satisfactory reproducibility (9itner et al., 466; 2eaveney, 466>).
#he two Audes then re-e?amined the responses on which they disareed. #his re-e?aminationprocedure eventually resulted in an interAude areement level of 4;; percent for both
WOM"s stimulants and its content. #hese classifications then became the benchmarks aainst
which the third Aude"s classifications were compared.
#he third Aude"s cateoriBation, compared to the benchmark, resulted in an interAude
areement of [email protected] percent for WOM"s stimulants and 6;.8 percent for its content. /ollowin
the procedure used for the second cateoriBation, the three Audes re-e?amined the responses
on which they disareed. ain, the re-e?amination procedure eventually resulted in an
interAude areement level of 4;; percent for both WOM"s stimulants and its content.

Results
#he survey respondents came from a relatively broad cross-section of the population. Of the
respondents, 56 percent were @> years of ae or less, @6 percent were between @< and =;
years of ae, and 5@ percent were =4 years of ae or over. /ifty-eiht percent of the
respondents were female and =@ percent were male. 'aucasians were heavily represented with65 percent of the respondents fallin in that ethnic cateory. Over 5> percent of the
respondents had a collee deree or hiher while another >; percent had at least some collee
education althouh they were not collee raduates. &n terms of marital status, =8 percent of
the respondents were married, =7 percent were sinle, and the rest were divorced, separated,
or widowed. #wenty-nine percent of the respondents were students and 48 percent were
professional or technical workers. Other occupations represented by the survey respondents
were business owner (=.; percent) farm manaer (@.8 percent) other e?ecutive or manaer
(>.7 percent) sales clerk or clerical worker (8.> percent) sales representative (;.< percent)
craftsworker, foreman, or machine operator (@.5 percent) laborer, service worker, or farm
worker (=.> percent) homemaker (=.> percent) retired (@.8 percent) unemployed (4.7
percent) and other (4>.5 percent).
#he survey responses focussed on a broad rane of services with a total of 7@ different service
industries represented. #hese service industries included such traditional services as banks,
hospitals, telecommunications services, barbers and hairdressers, home repair services, and
automobile repair shops. few of the responses also focussed on less traditional services such
as tannin salons and body piercin.
nalysis of the open-ended Duestions revealed ten cateories of stimuli that led to WOM
(#able &). #he receiver"s (of the communication) felt need was the most freDuently identified
WOM stimulus with >;.5 percent of the stimuli fallin into this cateory. /or e?ample, one
receiver asked specifically if the communicator knew of a ood travel aency that would help
him plan his honeymoon. nother conversation occurred Aust before pril 4> and focussed on
an individual"s need to find a ta? preparation service.
'oincidental WOM was the second most freDuently identified cateory with 48.= percent of
the stimuli. /or e?ample, one discussion that was classified as coincidental in nature bean
with a conversation amon co-workers and relatives about prenancies and babies. #his
discussion led to the transfer of neative information about a particular medical doctor.
nother coincidental communication bean with a eneral discussion of plans for the
weekend. #his conversation led to favorable comments about the Duality of a particular
restaurant and to a recommendation that the respondent eat there.
WOM that was stimulated by the communicator"s satisfaction or dissatisfaction with the
service was the third most freDuently identified cateory with 8.8 percent of the responses.
/or e?ample, one positive WOM occurred when a communicator shared her pleasure with the
Duality of pictures received from a particular photoraphy studio. neative communication
occurred after a communicator failed to have his automobile transmission satisfactorily
repaired even thouh he returned it to the repair shop on two different occasions.
omeone"s observance of the purchase or its outcome served as a stimulant to WOM
communication in percent of the cases. /or e?ample, a positive communication about a

and information related. &n the case of maBon.com, users employ powerful search enines
to find titles, receive lists of similar titles, have access to reviews, authors", publishers" and
readers" comments, subscribe to topic-specific notification services and, if all else fails,
interact with a prompt, helpful customer service staff by e-mail.
1irtual 1ineyards provides recommendations, information, and reviews of its wines. &tsofferins include products of smaller producers or limited vintae that can be difficult to find
in all but the most e?tensive wine shops. #hey offer food products as well, in addition to
collectors" and ift sets of food and wine. upplementin the value of their products are
collections of menus and recipes, complete with wine recommendations.
ome of the services offered by maBon.com and 1irtual 1ineyards are electronic substitutes
for the services offered by traditional retailers while other services are not readily available in
traditional outlets. Other service marketers can emulate these &nternet marketin strateies by
usin additional, supplemental, and free information to enhance the value of their offerins.
Coincidental conversation
'oincidental conversation was the second most freDuent stimulus of WOM communication in
the study, accountin for 48 percent of incidents. #his may also be the most difficult stimulus
to influence, in that service-related communication arises from eneral conversation rather
than specific discussion of the service. Marketin strateies directed at strenthenin ties
amon customers and potential customers may enable service marketers to take advantae of
this aspect of WOM (!einen and 2ernan, 468). /or e?ample, Macaroni 3rill restaurants
feature a festive atmosphere, e?troverted servers who use crayons to write their names on
paper tablecloths, and lare Aus of wine at each table. uch uniDueness may stimulate
customers to tell others about their consumption e?perience.

Communicator$s satisfaction or dissatisfaction
bout 6 percent of the WOM incidents in the study were stimulated by the communicator"s
satisfaction or dissatisfaction. inificantly, these incidents were more than twice as likely to
include neative, rather than positive, content. #hus, communicator-initiated WOM appears
more likely to be enerated by dissatisfaction than by satisfaction. #hese results are consistentwith !ichins (4685) and 9lodett et al.(4665) who have documented that inadeDuate redress
of rievances often leads customers to enae in neative WOM communication. On the
other hand, creatin hih levels of service Duality should lead to customer satisfaction and
stimulate positive WOM (9one, 466@).
#herefore, service marketers are presented with the double challene of stimulatin satisfied
customers" communication while limitin the impact of dissatisfied customers. 'learly, the
first step in this process is to offer service that is of hih Duality. #hen, service marketers
should insure that a viorous, responsive system for addressin customer complaints is in
place before enain in efforts to stimulate WOM.
Havin minimiBed the incidence and motivation for neative WOM, service marketers may
stimulate positive WOM by puttin prospective customers in contact with satisfied customers.
9anks have successfully stimulated interaction between current and prospective clients by
providin social activities for affluent senior citiBens, risin professionals, or people startin
new businesses. imilarly, securities firms have sponsored investment clubs for members
with similar financial obAectives and health care oraniBations have formed support roups for
patients facin common health problems or underoin similar treatment procedures. /irms
may also stimulate positive WOM from satisfied customers by creatin positive incentives for
referrals. Eiscounted services andKor referral fees are common tools for achievin this end.
/ileet al.(466=) also suest that marketers may use seminar sellin with both current clients
and potential clients in attendance.
/inally, it is important to note the dominant role of receivers in initiatin WOM
communication incidents. &n this study, WOM was far more likely to be initiated by receivers"
need for information than by communicators" satisfaction level. #his implies that, in the effort
to e?ploit service-related WOM communication, providers should focus much of their
attention on interceptin prospects" information seekin behavior rather than relyin primarily
on testimonials from satisfied customers. /or e?ample, *ewish Hospital of ouisville,
2entucky provides customers with a broad array of information and services throuh health
information centers that are strateically located in reional shoppin malls. /or e?ample,
consumers with hih blood pressure may be iven information about a $heart healthy% diet(Waner et al., 466=).
Someone$s observance of t!e purc!ase or its outcome
ome of the WOM in our study was stimulated by someone"s observance of the purchase or
its outcome ( percent) while other WOM was stimulated by an observance of the need for a
service (@.= percent). till other WOM was stimulated by the receiver"s satisfaction or
dissatisfaction (@.7 percent). ll three of these observations suest that service marketers
may develop strateies for rewardin people for referrals. #he techniDues for motivatin
referrals discussed earlier are relevant for these situations as well. &n addition, these incidents
illustrate the need to identify vividly the oraniBation with the completed service. &f possible,someone observin the benefits of a service purchase should be made aware of the identity of

the service provider. #he most obvious e?amples here are lawn sins for construction or
landscapin services or windshield shades for car repair or beautification shops. Other
instances miht include complimentary caps or #-shirts for those participatin in a clinic"s
wellness seminar, a tannin service"s basic packae, or a hotel"s freDuent uest club.
%o or more people collectively trying to select a service
Our research also suests that WOM may be stimulated when two or more people are
collectively tryin to select a service. Marketers may take advantae of this aspect of WOM
by aimin their promotion efforts at roups of people as well as individuals. #his observation
appears to be particularly relevant for restaurants since roups of people often make Aoint
decisions about where to eat. /or e?ample, restaurants miht offer discounts or
complimentary items to roups of four people from the same oraniBation at lunch time.
imilarly, discounts may be offered for special occasion parties or to roups of four or more
who have attended a local cultural or civic event durin the dinner period. lternatively,
business lunch clubs, in which members receive discounts for brinin business
acDuaintances for lunch, miht prove attractive. !estaurants miht also stamp freDuent uests"business cards with a discount offer that could be used by the uest or passed on to friends
andKor colleaues. #he oal of all these approaches is to have the sponsorin restaurant
included in roup discussions and decision processes concernin restaurant selection.
Marketing organi'ation$s promotional efforts
Only a small percentae of the WOM in our study was stimulated by the marketin
oraniBation"s promotional efforts. Moreover, the maAority of incidents triered by this
stimulus involved neative communication content. #his suests that service marketers may
need to establish the stimulation of WOM as a promotional obAective and, then, strateically
desin their promotions to accomplish this obAective. /or e?ample, M'& has successfully
stimulated WOM as well as referrals throuh its $/riends and /amily% proram.
lternatively, service marketers miht reassess their promotional obAectives relative to WOM
communication. #hat is, promotional effectiveness may be measured in terms of both the
number of WOM incidents enerated and the content of the communication. o matter the
stimulus which prompts a WOM incident, if the content of the communication is consistent
with the content of promotional material, the promotional effort may be deemed successful.
&ndeed, this miht be the more desirable result, as the role of communicator has now passed
from the less credible marketer to the more credible personal source of information.
(uality"oriented )*M
s indicated in#able &&, most of the WOM e?amined in our study focussed on Duality only.
WOM containin elements of both Duality and price was classified as value-oriented and
constituted the second larest cateory. relatively small portion of the WOM e?amined
focussed on price only.

it can meet or e?ceed these e?pectations on a reular basis. &f at all possible, Duality
uarantees should then be made in very clear lanuae, with very clear remedies for
deficiencies. n e?ample is Holiday &nn"s $complete satisfaction or your stay is free%
philosophy. imilarly, a restaurant miht offer ten-minute service for lunch, with free
appetiBers or desserts for loner waits. utomobile repair shops miht offer loaners or rides to
home or work for customers whose cars are not finished in one day. 9anks miht offer freelunches or tickets to athletic or cultural events to customers whose loan applications are not
processed in a specified period.
'learly, uarantees such as these are not possible in every service profession. :hysicians
cannot uarantee favorable response to treatment, nor can stockbrokers uarantee profitable
investments. However, these providers miht well be able to make process uarantees. /or
e?ample, physicians can uarantee office waits of no more than 5; minutes for patients with
appointments while stockbrokers may uarantee that trades will be e?ecuted within 5;
minutes. Eeviations from these promises may be rewarded with complimentary health-related
products or discounted commission rates.
#he offerin of such uarantees has several advantaes. /irst, it reDuires service providers to
consciously understand their capabilities relative to consumer e?pectations. econd, it
provides performance oals for the providers" employees and concrete benchmarks for
customers. #hird, and most relevant to this study, it provides concrete, memorable content for
measurin the value of service provided. #his, in turn, would set the conte?t for WOM
communication relative to the service oraniBation.
Price" and value"oriented )*M
number of other strateies are available to service marketers who wish to stimulate price-
and value-oriented WOM, particularly those who are low-price or hih-value providers in
their markets. 'ommunication obAectives for low-price providers may center on the provision

0imitations and directions for future research
#his research is subAect to several limitations. /irst, althouh the survey respondents
represented a relatively broad cross-section of the population, they were either students or the
acDuaintances of students. While the data collection method was consistent with previous
content-analytic research (2eaveney, 466>), there is no uarantee that the entire rane of
WOM was included in the study. #he elimination of appro?imately one-fourth of the survey
responses may have e?acerbated this limitation. /uture research may verify the
comprehensiveness of the data and the eneraliBability of the results.
econd, the research desin reDuested that respondents describe the last communication that
occurred. #his desin resulted in a description of the $last-remembered% communication
rather than the last communication that actually occurred. #his limitation is problematic if thecontent of more memorable communications is different from the content of less memorable

communications. #herefore, future research may utiliBe an e?perimental desin or other
research procedure to isolate the last communication that occurred rather than the $last
remembered% communication.
#he relative impact of positive versus neative communication on buyer behavior constitutes
still another avenue for future study. Much of the previous research pertainin to WOM in themarketplace has focussed on neative WOM and its influence on buyer behavior while less
emphasis has been iven to positive WOM. Our study made no attempt to delineate the
relative impact of positive or neative WOM on purchase behavior.
/inally, future research may focus on the interation of WOM into a more comprehensive
model of service purchasin behavior. uch a model would address the interrelationship
between WOM and such variables as satisfaction, output WOM (i.e. what the purchaser tells
someone else), intent to repurchase, perceived value, perceived Duality, perceived
performance, and initial purchase behavior.
12ecutive summary and implications for managers and e2ecutives
preadin the word - a key part of service communications stratey
Buying things is not something we do in isolation from those around us - family, friends,
workmates and neighbors. Shopping is a social experience and an important part of our lifes
acti!ity. So its no surprise that we share our experiences - good and bad - with others.
"roducts are adopted as much because of word-of-mouth communications as because of
acti!e promotions by the company making those products.
#espite this reality and managers awareness of word-of-mouth, we still feel somewhat
baffled by the processes in!ol!ed and the ways in which word-of-mouth communications
affect our business. $s a result of this bafflement, we take customers that arri!e on personal
recommendation but do little to encourage them to carry on the tradition of spreading the
word.
%irst, we need to understand why people are affected by and indulge in word-of-mouth
communications. Mangold et al.pro!ide us with some insights into the reasons for the
effecti!eness of word-of-mouth communications&
"eople need information about products and ser!ices. 'his is often the starting point
for (spreading the word). $ friend asks ad!ice about a decent restaurant, a goodplace to stay or for the name of a competent plumber. *e are delighted to be asked
and gi!e wholeheartedly of our ad!ice and expertise. Mangold et al. report that this
information seeking is the dominant stimulus for word-of-mouth communications.
Comments about ser!ices or products arise during casual con!ersation. "eople !ery
often mention experiences in the course of a normal con!ersation. +obody is seeking
specific information with a !iew to purchasing something but the information or
opinion arises - unsolicited - during the con!ersation. i!en the importance of
shopping, people will relate tales describing a good or bad experience.
*hat is clear from these two reasons is that people seldom - if e!er - set about passing on
information about a product or ser!ice without some reason. +obody wakes up and decides to

tell all their friends what a great place $ls estaurant is Managers who want to take
ad!antage of word-of-mouth communications need to take a more subtle approach.
Suggestions for stimulating our customers to recommend our ser!ice or at least talk about it
might include&
0?hortation.'heres no harm in asking customers who express satisfaction to tell
their friends. 'hey might be more inclined to do so if you ask them and it will surely
do no harm.
&ncentive.Mail order companies and subscription maga/ines ha!e used the
recommend-a-friend incenti!e as an effecti!e way of bringing in new custom. By
offering a gift, discount or other reward to customers who recruit new customers
pro!ides a positi!e benefit to the person (spreading the news). 'here is a limit to the
approach since 0as multi-le!el marketing and pyramid selling ha!e shown1 there is a
fine line between a fair incenti!e and exploiting friendships.
#aretin opinion formers. Certain people get listened to more or simply speak to
more people than most folk. *e can call these (opinion formers) since their influenceis greater because of the breadth of their contacts. "riests, publicans, postmen and the
$!on lady all speak to large numbers of people. 'argeting your message here can
ha!e an effect that exceeds a similar but untargeted approach.
peakin to clubs. 'here are plenty of local organi/ations that need speakers each
and e!ery week. 2ffering yourself as a speaker can result in positi!e and fa!orable
word-of-mouth. 3!en better - offer a discount or other incenti!e to the people you
speak with. +ot only will they be more likely to use you but it creates a further positi!e
spin and encourages the listeners to (spread the word).
ettin up a club. %ound your own club. 4et your customers run it and pro!ide
facilities, ad!ice and other support. 'heyll feel closer to you - almost a part of the
business - and be more inclined to tell their friends. 'he club neednt be too formal
but should ha!e a purpose and someone to lead it.
!unnin a newsletter.+othing too fancy. 5ust a few pages of thoughts, ideas, product
information and customer comment. et customers to contribute with letters, stories
or ideas. 'hese days you can e!en extend the newsletter by setting up a *eb site.
Mangoldet al.gi!e a few examples of how this can succeed in getting people to talk
about your product or ser!ice.
3ivin away freebies.eward your regular customers with some free product or
ser!ice. #ont make this too formal a process, simply take ad!antage of one of their
!isits to thank them by gi!ing a free meal, oil change or whate!er you offer. 6ou can
be sure that they will tell their friends 7ust how good you are and maybe e!enencourage their friends to try you out.
'hese are 7ust a few examples of how to get people talking about what you do. 'here are
hundreds of other ideas inside your head. Sit down. %ish out a few thoughts and try them out.
Most ser!ice organi/ations are part of the community. $ct like you are and you will get the
benefit of others treating you as a friend rather than as a mere business. $nd once youre a
friend people want their other friends to meet you.
