In promotion and of advertising, a testimonial or show consists of a person's written or spoken statement extolling the virtue of a product. The term "testimonial" most commonly applies to the sales-pitches attributed to ordinary citizens, whereas the word "endorsement" usually applies to pitches by celebrities.
Growing a successful company requires marketing, promotions and advertisements to bring attention to your product and ultimately increase your sales. Advertisements can include direct mail campaigns, classified ads, flyers and commercials.
Testimonials are written or spoken statements that certify or authenticate the quality or worthiness of a product or service. These statements aren't written by a company staff member, an ad agency, or the owner of the company. Rather, testimonials are feedback or comments submitted by actual customers
You can feature customer testimonials on different types of advertisements. If you develop a website for your business, include a page specifically for testimonials. Contact old and present customers and ask them to provide a brief statement expressing their satisfaction with your service.
