A marketing firm advises a local restaurant to focus its advertising on social media influencers, claiming this strategy will significantly increase the restaurant's customer base. The firm cites recent data showing that 70% of the restaurant's current customers follow at least one local food influencer. Which of the following, if true, would most seriously weaken the marketing firm's claim?
- AThe restaurant's menu and atmosphere are already highly rated by its existing customers.
- BThe restaurant's current customers discovered the restaurant primarily through word-of-mouth recommendations.
- CSocial media advertising campaigns are generally less expensive than traditional print advertisements.
- DMany of the local food influencers followed by the restaurant's customers also promote competitor restaurants.
Show answer & explanationAnswer & explanation
Correct answer: B. The restaurant's current customers discovered the restaurant primarily through word-of-mouth recommendations.
The marketing firm assumes that because current customers follow influencers, influencers are an effective channel to *attract new customers*. If current customers found the restaurant through word-of-mouth, it suggests their influencer following is a correlation, not a cause of their patronage, and thus targeting influencers might not be effective for *growing* the customer base.
Why the other options are wrong
- A. High ratings are good for retention but don't explain how *new* customers are acquired, which is the focus of the marketing firm's claim.
- C. This addresses the *cost* of social media advertising, not its *effectiveness* in increasing the customer base.
- D. This suggests that influencer marketing might not be *exclusively* beneficial to this restaurant, but doesn't directly weaken the idea that it could still *increase* the customer base.
Challenging Causal Effectiveness
To challenge the effectiveness of a proposed cause, show that the observed correlation is not causal, or that other factors are the true drivers of the desired outcome.
- Correlation does not imply causation.
- Identify confounding variables.
- Look for temporal precedence issues.
Memory trick: Don't just follow the crowd, check if the influencer's shout is truly loud!
