There are four main ways for companies to become socially responsible marketers: 1) corporate social responsibility, 2) socially responsible business models, 3) cause-related marketing, and 4) social marketing. Corporate social responsibility involves ensuring legal and ethical behavior as well as social responsibility and sustainability. Socially responsible business models focus on innovating solutions and values in a socially conscious way. Cause-related marketing links company contributions to causes with customer transactions. Social marketing furthers causes through programs run by non-profits or governments. Effective social marketing involves understanding target audiences, setting objectives, developing marketing strategies, and evaluating programs.
