  • It remains one of the most trusted forms of marketing, since recommendations from people we know carry more weight than advertising.
  • It's increasingly amplified and made visible through online reviews and social sharing, extending its reach beyond just direct personal conversations.

How It Works

  1. A satisfied (or dissatisfied) customer shares their experience with others, organically.
  2. This spreads through personal conversations, and increasingly through online reviews and social media.
  3. A business can encourage this by delivering a genuinely excellent, memorable experience worth talking about.
