Content marketing strategy, content strategy, and content plan.
People often use these terms interchangeably (which is understandable, as the lines are somewhat blurry), but each is a bit different:
Content marketing strategy
At its core, your content marketing strategy is your “why.” Why you are creating content, who you are helping, and how you will help them in a way no one else can. Organizations typically use content marketing to build an audience and to achieve at least one of these profitable results: increased revenue, lower costs, or better customers.
