Advocacy advertising is a form of marketing used primarily by nonprofit organizations and private groups with the goal of swaying public opinion to support a particular cause or message. It differs from commercial advertising because it does not promote a product or service.

Advocacy advertising is a promotional campaign to market your brand name by supporting a social cause or message. Businesses advocate for a particular cause, viewpoint, or social issue to raise awareness, shape perceptions, and mobilize support. Nonprofits often implement this basic marketing strategy to sway public opinion.
