Substantive Domains

The second pillar is the substantive domain: the phenomena marketing actually studies. Where the construct pillar asks what concepts mean, the substantive pillar asks what is going on in the world—how brands accrue value, how prices are set and perceived, how advertising works, how customers are acquired and retained, how innovations diffuse and markets are entered, how communities form online and influence spreads. These are the contexts that motivate the theories and supply the data.

A field is only as comprehensive as the phenomena it takes seriously, so this part is deliberately broad. It spans the marketing-mix decisions (product, price, promotion, place), the customer-management problems (experience, relationships, lifetime value), the sectors and contexts that impose their own logic (services, retailing, B2B, health, platforms, public policy), and the communication and influence dynamics that increasingly run through digital environments. Each domain is a standing invitation for construct-level theory and methodological care—the other two pillars—to be brought to bear.
