Despite rapid and sustained development of electronic commerce, many companies doing e-business are still in the investment and brand-building phase and have yet to show a profit. However, as e-businesses shift their focus from building a customer base to increasing revenue growth and profitability, they should re-evaluate their current business strategies, if any, and develop strategies that provide a clear path to profitability. This study uses McCarthy’s four marketing mix model and Porter’s five competitive forces model to identify strategies for Internet companies that respond to the five competitive forces and thereby achieve a competitive advantage. The study provides significant new insights into the development and implementation of e-business strategies that contribute to increased profit.
