What I got from this book, in a few words: Don't forget that the intangible matters too.
Nowadays, because of the digital revolution, everything in marketing is about data, ROI, CTR, and quantifying every step you take so that you can justify it. This book provides a great methodology on how to give value to ALL types of efforts, and shares great research on why this matters (especially for the long term).
Also, this is one of the only books about marketing (and I've read quite a few) that shares a concrete methodology on how to value brands and marketing efforts.
Easy read, very structured, and valuable information.
Some of my highlights:
"Strong brands also come to mind quickly. They have multiple connections in consumers' memories, and this gives them a memory-encoding advantage. The more links a brand has, the easier that brand is to recall when a need occurs."
"Attention is not enough; people have to 'get it'."
"...strong brands clearly and easily present themselves to consumers with no contradictory, confusing, or excessive information."
