The document discusses common mistakes made with loyalty programs. It identifies 5 key mistakes: 1) Having a complex onboarding process rather than keeping it simple; 2) Having a "one size fits all" approach rather than tailoring the experience to individuals; 3) Having lengthy feedback cycles rather than providing feedback as soon as possible; 4) Offering rewards that are not the "right" rewards for customers rather than focusing on motivation; 5) Lacking social elements rather than leveraging the power of human interaction and social proof. The document advocates designing loyalty programs based on motivation principles to drive high customer engagement and value.
