Do consumers trust word-of-mouth more than advertising?

Yes. Nielsen research is widely cited for finding that around 92% of consumers trust recommendations from people they know over any form of advertising, and roughly 83% trust recommendations from friends and family — making peer word-of-mouth the most trusted source. This is the core reason brand ambassadors who create authentic, person-to-person interactions outperform impressions alone.

How much of purchasing is driven by word-of-mouth?

McKinsey has identified word of mouth as the primary factor behind roughly 20% to 50% of all purchasing decisions, with the highest influence on first-time purchases and considered or higher-risk categories. Brand ambassadors are a way to manufacture authentic word-of-mouth at scale.

Are brand ambassadors effective compared to paid ads?

Research from BCG and others suggests word-of-mouth and peer recommendation can be several times more effective than equivalent paid media impressions. A trained brand ambassador delivers a trusted, face-to-face interaction — the format consumers trust most — which is why brands deploy them for trial, education, and conversion.
