This document discusses inbound and outbound marketing. It defines inbound marketing as "pull marketing" where customers are attracted to a business, versus outbound marketing which "pushes" marketing directly at customers. Key differences are that inbound marketing earns attention without interrupting customers, focuses on search and word-of-mouth, and makes customers feel in control of buying. Outbound relies more on tactics like advertising. The document also covers related concepts like the first moment of truth (3-7 seconds of shelf exposure), zero moment (online research stage), and advocate moment (positive word-of-mouth).
