Testimonials are positive statements or reviews from customers about a product or service. They help potential buyers understand the experiences of others and can build trust in a brand. For example, if someone shares their satisfaction with a restaurant they visited, it can encourage others to try it out. Businesses often use testimonials in their marketing to showcase happy customers. These endorsements can be found on websites, social media, or advertisements. When people see real feedback from others, like a customer praising a new gadget, they are more likely to feel confident in making a purchase.
