To develop an online presence, most companies adopt various e-business models. Royal Scotland Bank (RBS) has adopted B2B and B2C models to expand its business and offer services to consumers. The B2B model enables RBS to provide data management, in-depth analysis, and interactive marketing solutions to businesses, while the B2C model allows it to offer online banking and mobile banking options to customers. By implementing these models, RBS can set its marketing strategy, enhance its profit margin, and improve customer loyalty. Additionally, RBS needs to address ethical responsibilities and security measures to keep customer data safe and secure.
