Word of mouth marketing is a form of marketing that relies on conversations between people. Word of mouth marketing relies on satisfied customers and the desire to spread information they’re passionate about to their friends and family. This is because if someone likes something, chances are that they’ll tell at least one person. It’s easy for word-of-mouth marketing to be effective because it doesn’t require any upfront spending and it’s cost-effective in the long run. The downfall to this type of marketing is that it can take time for people to hear about your product or service and there is no guarantee that they will like what you have to offer.
