    Why are they INFLUENCED? CONSUMER CONSUMER

    • observe & measure WOM as source of customer info
    • facilitated online (automated)
      • monitor chatrooms, communities, review sites
      • benchmark / compare with competitors
    marketer
  • 18. Consumer Consumer FACILITATE marketer
    • Provide ways to WOM (e.g., reviews, forums, VCs)
    • makes relevant information available for consumers
    • BUT: difficult to control negative WOM
  • 19. MODERATE Consumer Consumer marketer
    • Influence WOM content, frequency & targeting
    • WOM as part of MARCOMS
      • design campaigns to stimulate buzz
      • what is the effect on WOM?
      • effect on company & customer reputation
  • 20. Consumer Consumer PARTICIPATE marketer
    • Participate in WOM
    • pro-active: inform discussion (expertise, news)
    • reactive: respond to criticisms
    • BE OPEN : don’t hurt yourself or the image of WOM!
  • 21.
    • Ryu & Feick (2007)
    • “ would you advise product X to consumer Y?”
      • higher likelihood with “strong ties”
      • higher likelihood with higher rewards (20% vs. 10% of price)
      • reward especially increases likelihood of weak-tie referrals
    STIMULATING WOM WITH REWARDS?
  • 22. WOM is defined as interactions.. - “between perceived non-commercial sources” (Brown et al. 2005) - “by individuals not actively engaged in selling the product” (Godes et al. 2005) “ The power and the significance of everyday word of mouth lie mainly in the speaker’s lack of material interest” (Dichter 1966) => What about incentives / rewards for WOM ??? STIMULATED WOM: ULTERIOR MOTIVE
  • 23. behavior that is congruent with self-interest leads to inferences about the presence of ulterior motives (UM) (Vonk 1998. Friestad & Wright 1994) When UM are more accessible, consumers become suspicious, and it becomes more likely that consumers categorize agent behavior as a persuasion attempt (rather than a “normal” social interaction) => decreased effectiveness of the referral => decreased liking (perceived sincerity) of the target (Campbell & Kirmani 2000) P1: The impact of WOM decreases when rewards are given ULTERIOR MOTIVES
  • 24. Without rewards, Frank is seen as…. friendly, helpful, social, enthusiastic, nice, price conscious, reliable With rewards, Frank is seen as…. pushy, suspicious, hidden agenda, salesperson, insincere, calculating, weird, dishonest, sneaky, VVD-er (!) some thoughts (for sake of illustration)
  • 25.
    • P2:
    • Tie strength moderates the negative effect of UM on impact of WOM
    • strong ties relationships are more credible and characterized by intimacy, support and trust (Brown & Reingen 1987, Frenzen & Davis 1990, Levin & Cross 2004)
    • we are less likely to infer UM from the behavior of strong ties
    • impact of WOM is reduced by rewards, but less if sender is a strong tie
    INTERACTION I: STRENGTH OF SOCIAL TIE
  • 26.
    • 158 consumers from the Netherlands
    • Product: mobile phone provider
    • 2 x 2 between-Ss: Tie Strength (weak / strong) * Reward (no / yes)
    • MEASURES :
    • thought listing – coded for UM thoughts
    • ratings (on 7-point likert-scales) of evaluation of brand & sender
    STUDY 1
  • 27. UM THOUGHTS
  • 28. BRAND EVALUATION
  • 29.
    • Rewards reduce the impact of WOM on consumers:
    • increase in perceived ulterior motives (“he’s in it for the money”)
    • less favorable evaluation of sender
    • less likely to comply with offer
    • BUT: only when tie-strength is weak.
    • Effects do not occur when WOM is between strong ties
    CONCLUSION I
  • 30. P3: SYMBOLIC rewards (e.g., donation to charity on behalf of sender) do not benefit the sender. Therefore: they evoke less UM, and leave the impact of WOM intact. INTERACTION II: TYPE OF REWARD
  • 31. 120 students from S. Korea Product: English Language institute 3 x 2 between Ss: Tie Strength * Reward (no / monetary / symbolic) Tie strength: Identify “ close friend ” or “ casual acquaintance ” (initials) Reward: 30,000 KWON as gift voucher for sender or donation to charity MEASURES : ratings of: Product & sender evaluation & perceived UM (similar to study 1) STUDY 2
  • 32. BRAND EVALUATION (similar results for source evaluations)
  • 33.
    • Negative effect of rewards are reduced or even disappear when sender is not benefiting on the expense of the receiver:
    • - reduces perceived ulterior motives (“I don’t think he’s in it for the money”)
    • evaluation of sender and product are not affected
    • Study 2 replicates effect of tie strength in S. Korea
    CONCLUSION II
  • 34. P4: initiative taking moderates the negative effect of UM salience on impact of WOM we are more likely to suspect UM if WOM is a spontaneous action of the sender. On the other hand, if WOM is actively sought, we have less reason to doubt the sincerity of the sender (Gatignon & Robertson 1985; Kirmani & Campbell 2004, Mazzarol et al. 2007) INTERACTION III: INITIATIVE
  • 35.
    • 117 students from USA
    • Product: mobile phone provider
    • Sender: “Kim, who you just met at a party”
    • 2 x 2 between Ss: Initiative (sender / receiver)* Reward (no / yes)
    • Initiative in scenario:
    • “ she mentions cell phone cost, and tells about her new provider” (sender) or “you mention… and she tells about her new provider (receiver)
    • Reward: $20 gift voucher for sender
    • Ratings of:
    • Participation : “likely to give e-mail ?” (7-point likert scale )
      • WOM sender ; Perceived UM (similar to study 1 & 2)
    STUDY 3
  • 36. BRAND EVALUATION (similar results for source evaluations)
  • 37.
    • Negative effects of rewards are reduced or even disappear when WOM is initiated by the receiver:
    • - Increases relevance & reduces likelihood of ulterior motives
    • evaluation of sender and product are not affected
    CONCLUSION III
  • 38.
    • Rewards may reduced sender integrity & WOM impact
    • - more so for strangers than for friends
    • - less so if WOM is initiated by receiver
    • - less so if rewards are symbolic (donations to charities)
    • SO: BUZZ CAREFULLY (respect unique C2C characteristics)
    • - rely on strong ties
    • - use “natural” interactions
    • Dilemma: rewards stimulate weak-tie, sender-initiated WOM…
    • => Net effect may depend on specifics of the context
    REWARD, BUT CAREFULLY
  • 39.
    • 1. SENDERS talk when you give them something to talk about:
    • superior, innovative & relevant products with benefits that are easy to communicate
    • emotions and social relationships
    • low prices / value for money “smart shopper feelings”
    FOUR “RULES OF WOM”
  • 40.
    • 2. SENDERS talk because they feel like it:
    • Being delighted
    • Presenting themselves (attention, status, image)
    • Helping you (“if you’re worth it”)
    • Helping other consumers
    • => Product enthusiasm is most important
  • 41.
    • 3. RECEIVERS are influenced because they get information that is:
    • relevant (substitute for own experience)
    • reliable (strong ties, no strings attached)
    • Customized (timing, content, amount, tone)
    • And because they remember WOM better than other media!
  • 42.
    • 4. WORD OF MOUTH can be managed
    • observe & measure, facilitate, moderate, participate
    • Make sure that your WOM is still
    • “ social sharing of relevant information among friends”
    • Be open about your activity and ask your customers to do the same
