What You'll Learn
How Brands Grow challenges many traditional marketing beliefs and presents marketing as a scientific discipline based on real data. Drawing on decades of research from the Ehrenberg-Bass Institute, Byron Sharp explains that brand growth does not mainly come from increasing loyalty among existing customers. Instead, brands grow by reaching more buyers and increasing market penetration.
The book introduces several important marketing laws, such as the Double Jeopardy Law, which shows that smaller brands naturally have fewer customers and slightly lower loyalty. It also explains that consumers often practice polygamous loyalty, meaning they regularly buy multiple competing brands rather than staying loyal to just one.
Sharp argues that successful brands focus on mental availability (being easily remembered) and physical availability (being easy to find and buy). By consistently building distinctive brand assets, expanding distribution, and reaching a broad audience, companies can increase their chances of being chosen in real buying situations.
