Word of mouth
Word of mouth is when people recommend a business to others through casual conversation rather than paid advertising. It is powerful because recommendations from friends carry trust that ads cannot match, making word of mouth one of the most effective ways to grow a service business.
Word of mouth is the oldest and often the strongest form of marketing. When a neighbor says a plumber did great work, that recommendation lands harder than any ad, because it comes with personal trust and no sales motive.
You earn word of mouth by doing excellent work and being easy to deal with. You amplify it by asking happy customers for reviews and referrals, which turn private praise into public proof that reaches many more potential customers.
