Explain the concept of the marketing mix (4Ps) and how digital marketing has expanded this framework to include additional elements.

The marketing mix, originally defined as the 4Ps (Product, Price, Place, Promotion), outlines the key components of a marketing strategy. Digital marketing has expanded this framework to include additional elements like People, Processes, and Physical Evidence (7Ps). The expansion addresses the complexities of service-oriented and digital businesses, emphasizing the importance of customer experience, streamlined processes, and tangible proof of quality. This holistic approach helps businesses adapt their strategies to the digital landscape.
