The way we shop is changing and marketing strategies are simply not keeping pace. Whether we’re shopping for corn flakes, concert tickets or a honeymoon in Paris, the Internet has changed how we decide what to buy. Today we’re all digital explorers, seeking out online ratings, social media-based peer reviews, videos, and in-depth product details as we move down the path to purchase. Marketing has evolved and modern marketing strategies have to evolve with the changing shape of shopping.
At Google, we call this online decision-making moment the Zero Moment of Truth — or simply ZMOT.
