Reputation for Sale

Reputation for Sale reveals how online ratings, reviews, and social proof evolved from simple trust signals into a powerful system that shapes what people buy, believe, and value. Alexander H. Blackwell explains how platforms turned public approval into a measurable asset, making reputation portable, visible, and profitable. Drawing on the mechanics of digital culture and platform economics, this book shows why numbers feel more objective than judgment, how visibility can matter more than accuracy, and why social proof is so effective at steering behavior. Readers will see how star ratings, seller scores, follower counts, and review systems influence consumer choices and business strategy while quietly reshaping public trust. Clear, timely, and thought-provoking, Reputation for Sale gives readers the tools to recognize the forces behind online approval and understand how reputation is bought, engineered, and exploited in the digital marketplace.
