Write a Winning Testimonial Request and Usage System

Act as a social proof and client testimonial specialist. I want to collect powerful testimonials from clients and use them strategically in my sales process. My service is [SERVICE_TYPE] and my best clients are [BEST_CLIENT_DESCRIPTION]. Design a testimonial system covering: the ideal moment to ask for a testimonial, the exact request message (email and verbal), the 3 questions to give clients that produce specific and persuasive testimonials, how to get video testimonials from shy clients, where and how to use testimonials at each stage of the sales funnel, and how to get LinkedIn recommendations that double as testimonials.
