Word of mouth

Word of mouth is informal communication between individuals about products, services, or organizations. It can shape awareness, reputation, and purchasing decisions through personal accounts and recommendations.

Opinion leadership: The process by which influential individuals shape others’ attitudes or choices through communication. Some people’s recommendations carry greater weight because others regard them as knowledgeable or credible.
Referral marketing: A marketing strategy that encourages existing customers to recommend a business to others. It turns personal recommendations into a deliberate customer-acquisition channel.
Advertising: Paid communication intended to promote a product, service, idea, or organization. Unlike advertising, word of mouth usually arises between individuals rather than from a paid media placement.
Social proof: A tendency to treat other people’s behavior or judgments as evidence of what is appropriate or valuable. Recommendations provide social evidence that can reduce uncertainty about an unfamiliar offering.
Social network: A structure of people or groups connected by social relationships. Word of mouth travels along these ties, reaching people through existing relationships.
Influencer marketing: Marketing that uses people with an audience to promote products, services, or brands. It borrows the persuasive force of personal recommendation, often through public-facing creators.
Public relations: The practice of managing relationships and communication between an organization and its publics. Organizations can shape public communication, but word of mouth is exchanged informally among individuals.
Brand reputation: The collective evaluation of a brand held by its stakeholders and the public. Repeated conversations can strengthen or damage how people regard an organization.
Homophily: The tendency for people to form relationships with others who resemble them. Similar tastes and identities can make recommendations between connected people especially persuasive.
Customer advocacy: Customer behavior that actively supports or recommends a company or its offerings. Advocates generate favorable conversations beyond their own transactions.
