What's it about?

How Brands Grow (2010) challenges many common marketing beliefs using decades of evidence on how people actually buy. Byron Sharp shows that brands grow mainly by reaching more buyers, including light and occasional ones, rather than by building intense loyalty among a few. The book explains why mental and physical availability, making a brand easy to think of and easy to buy, matter more than many popular strategies.

Key ideas

Brands grow mainly by reaching more buyers, not by deepening loyalty among a small group of existing customers.

Mental availability means making a brand easy to think of when a buying moment arrives.
Physical availability means making a brand easy to find and buy where people shop.
Many popular marketing beliefs are challenged by decades of evidence on how people actually buy.
