Battlecry: Winning the battle for the mind with a slogan that kills.

Effective slogans rely on sound rather than just words, utilizing techniques like rhyme, alliteration, repetition, reversals, and double-entendre to enhance memorability. The book explores why many slogans fail to employ these tactics, revealing a survey showing only a small fraction effectively use them. It emphasizes the importance of pairing a compelling slogan with a strong visual element, or "visual hammer," to reinforce brand recognition. Together with the author's previous work, this book provides insights into crafting impactful advertising strategies.
