Key Takeaways
- Culture influences the effectiveness of celebrity endorsements. In high-power distance cultures like India, people value hierarchy more, which makes celebrity endorsements more effective. In lower power distance cultures like the US, consumers are less influenced by celebrity status.
- Consumers tend to trust celebrities more and view them as experts in high power distance cultures, which enhances the impact of ads. In low-power distance cultures, marketers must ensure celebrity endorsements are backed by real expertise to gain the trust of consumers.
- Celebrity endorsements are more effective for low-cost everyday products like chocolates than for luxury items, where consumers take more time to think before buying.
