Book excerpt: Winfluence by award-winning digital strategist Jason Falls, is THE authoritative book about influencer marketing from the perspective of businesses and brands. An invaluable guidebook for marketing managers, small business owners, marketing consultants and agencies alike, the book explains how influencers came to be, how they came to be so powerful, why so many brands are counting on influencer marketing for business success and how anyone who is not, now can. This book not only explains the who, what, when, where, and why of influencer marketing but then adds the how—more specifically and predictably than other books can hope for. It offers detailed guidelines, case studies, cutting-edge ideas, how-tos for measuring success, and more to help any business owner, marketer, agency account person, or digital strategist see and seize the opportunity to drive business results. Through a series of narrative stories, interviews, and case studies, the book illustrates how to take what many people consider good influencer marketing to a new level of success from a long-tail perspective—not short-term, one-off executions.
