Customer feedback is defined as information or opinions provided by customers about their experience with a company, product, service, or brand. This feedback can be in the form of online reviews, surveys, social media comments, or even face-to-face conversations. Positive customer feedback is often used by businesses to improve their products or services, while negative feedback can be used to help identify areas where improvement is needed. Either way, customer feedback is an important part of any business and should be taken seriously.
