In the very competitive retail environment of today, where consumers are more informed and socially conscious than ever, success in business depends not just on what you sell but also on how you sell it. Ethics in marketing and brand management are now a strategic necessity rather than a decorative virtue in developing countries like Nigeria, where customer faith in organisations and brands is still brittle. This necessity has animated a global retail shift toward ethical consciousness. From the notion of fair trade to transparent sourcing of materials, ethical marketing now shapes how customers perceive value.
