From a practical standpoint, this study provides policymakers app developers, and marketers with useful suggestions. Advertising that seamlessly integrates with the user experience uses dynamic personalization and makes use of social proof should be given priority by marketers. Contributions to theory include advancing our understanding of consumer behavior and the function of digital media in developing economies which lays the groundwork for future research on the dynamics of advertising in comparable cultural contexts.
