Which statement best describes virality in marketing?

• A. It relies solely on paid promotions to grow.
• B. It is the result of deterministic engineering without user input.
• C. Growth driven by customers sharing with others; incorporate shareable features, incentives, and social proof.
• D. It requires zero strategy or channels.

Answer: (C)

Virality in marketing is growth that mainly comes from customers sharing the product with others. The best approach is to build features that people want to share, offer incentives for sharing or referrals, and show social proof that makes others want to join. When a product is easy to share and valuable enough that users want to tell their friends, growth becomes self-reinforcing as more people bring in more people. It’s not just about paid promotions or top-down campaigns, and it isn’t something that happens if you design it as a deterministic, user-free engine. Nor can you expect zero strategy or channels to produce results; you need deliberate design choices that encourage sharing, referrals, and observable credibility to spark word-of-mouth.
