Word of Mouth is a term for passing information, stories and so on between different people via oral communication. This is one of the oldest forms of communication, and Word of Mouth can be incredibly effective in marketing.
Encouraging consumers to discuss your brand through Word of Mouth works so well because consumers trust each other more than brands, since they don’t feel they’re being marketed or sold to by friends and family.
While you can run marketing campaigns to drive Word-of-Mouth marketing, simply focusing on post-purchase customer nurturing helps to generate loyal customers and even brand advocates. Advocates will actively encourage other consumers towards your brand.
One downside of marketing through Word of Mouth is that it’s hard to track success and progress due to lack of tangible data.
