Answer: Positive testimonials tend to lead to more buyers.
Explanation: A testimonial is a person's own words or story about how a product or service they bought affected them personally (first hand experience). An advertiser will present someone's positive experience with their product or service in order to get more people to buy into its goodness. People tend to believe an ordinary citizen's own words about their use of the product more than they would believe the advertiser talking highly about the product. This is because most people think that an advertiser is only pushing the product and possibly exaggerating its good benefits in order to sell more of it. The use of positive testimonials does usually increase sales of the product or service.
