"B2B" and "B2C" refer to different online business models. B2B (Business-to-Business) involves transactions between businesses, focusing on wholesale, supply chain, and service-oriented companies. B2C (Business-to-Consumer) targets individual consumers, offering products and services directly. Each model necessitates distinct marketing strategies and customer engagement approaches. B2B requires building long-term partnerships and trust, while B2C emphasizes brand loyalty and consumer behavior. Understanding these distinctions is crucial for businesses to effectively reach and serve their intended audiences.
