Lobbying differs from advocacy primarily in its methods and goals. While both seek to influence public policy, lobbying involves direct interaction with lawmakers or government officials, often conducted by professional lobbyists representing specific interests. It usually focuses on achieving particular legislative outcomes or regulatory changes. In contrast, advocacy encompasses broader efforts to raise awareness, mobilize public support, and encourage change through grassroots campaigns or education. Advocacy often targets societal norms and values, while lobbying is more transactional and generally seeks tangible legislative results.
