The platform economy has become a defining organizing logic of global digital marketing, restructuring how value is created, exchanged, measured, and governed across borders. Digital platforms—search engines, social networks, marketplaces, app stores, short-video networks, and messaging “super-apps”—now function as multi-sided intermediaries that orchestrate interactions among consumers, brands, creators, developers, and service partners. Building on platform and ecosystem scholarship, this paper synthesizes how global digital marketing ecosystems emerge from (i) platform governance and rules, (ii) data and identity infrastructure, (iii) algorithmic matching and ranking, (iv) monetization models such as advertising auctions and revenue shares, and (v) cross-border regulatory constraints. We develop an integrative framework that explains how platforms shape international marketing strategy through network effects, modular complementor ecosystems, and feedback loops between consumer behavior data and automated optimization. The paper proposes testable propositions linking platform governance openness, data portability, and cross-platform interoperability to international campaign performance, market entry speed, and brand resilience. We conclude with research directions and managerial implications for brands operating in a multi-platform global landscape characterized by rising privacy regulation, measurement fragmentation, and increasing platform power.
