B2B marketing differs from consumer marketing in that it focuses on promoting products and services to other businesses rather than individual consumers. Key aspects of B2B marketing include targeting specific decision makers within an organization, emphasizing how products and services can help businesses achieve their goals, and building long-term relationships through personalized communication and support. The needs and buying processes of businesses tend to be more complex than consumers, requiring B2B marketing to provide thorough information and address multiple stakeholders within an organization.
