**Who This Book Is For:**

This book is for marketers, brand managers, business owners, and anyone responsible for growing a brand. It is also for students of marketing who want to understand how markets actually work rather than how textbooks claim they should work. If you have ever wondered why your carefully targeted campaign failed to move the needle, or why your loyalty program did not produce the growth you expected, this book will explain what was really going on.

Byron Sharp wrote How Brands Grow to address a fundamental problem: the gap between what marketing practitioners believe and what decades of empirical research actually shows. Sharp is not a marketing guru offering opinions. He is a professor and the director of the Ehrenberg-Bass Institute, one of the world's leading centers for marketing science. His work is funded by major corporations including Coca-Cola, Mars, and Nielsen, precisely because these companies want answers grounded in evidence rather than intuition.

They buy from a repertoire of brands rather than committing to a single favorite. They are influenced by advertising in ways that are subtle and cumulative, not immediate and persuasive. This mismatch between marketing theory and consumer reality leads to wasted spending. Companies invest in differentiation when consumers barely perceive differences. They build loyalty programs that reward…
