About the Book

Viral marketing is not luck, magic, or a lottery ticket. It is the predictable outcome of understanding human psychology, social networks, and platform dynamics, then designing products, content, and campaigns that align with those forces. This book synthesizes academic research, historical case studies, real-world frameworks, and direct insights from growth leaders at companies like Duolingo, Airbnb, Dropbox, and Notion into a complete guide for anyone who wants to build marketing that spreads on its own. From the psychology of why people share to the mechanics of referral systems, from platform-specific tactics to ethical guardrails, you will learn how to engineer virality deliberately and sustainably.
