Customer Loyalty is how supportive of a brand customers are and how likely they are to stay with one brand vs flip flopping to a competitor.

Reviews are both positive and negative feedback about a brand or product that customers leave for others to see. Ensuring a company responds constructively to reviews is important to show they care about what customers think of their brand.

Customer Feedback are comments made by customers that gives insights about what they think about a brand or product.

Response Rate is what percentage of customers respond to a survey. This will let you know if it is quality research that you are able to use or if the sample size is too small.
