Testimonials are customer quotes that can be used to improve the credibility of your business. When potential customers see that others have had positive experiences with your products or services, they are more likely to trust you as well. Testimonials can come from a variety of sources, including online reviews, word-of-mouth recommendations, and personal anecdotes. If you're not sure where to start, try reaching out to some of your happiest customers and asking them to write a few sentences about their experiences.
