Short answer
Customer advocacy is the use of programs that mobilize happy customers to provide references, reviews, testimonials and case studies that influence prospects. Advocates may also speak at events or join referral programs. Because buyers trust peers more than vendors, advocacy strengthens credibility and can shorten sales cycles in B2B markets.
