Digital purchasing behavior varies significantly across cultural settings due to differences in values, risk perception, social influence, communication norms, and technology adoption preferences. Guided by Hofstede’s cultural dimensions, this research analyzes how cultural factors shape consumer behavior on digital platforms across diverse national contexts. Data was collected through surveys across eight countries, interviews with e-commerce executives, and secondary datasets on digital adoption rates. Findings suggest that high-individualism cultures prioritize convenience and personalization, while collectivist cultures rely more on peer influence and community reviews. Uncertainty-avoidant cultures exhibit higher reliance on secure payment methods and government-regulated platforms. A cultural behavioral model is proposed to guide international digital marketing strategies.
