Before you start co-creating content, you need to align on your goals and expectations with your co-creator. You need to agree on the purpose, format, tone, and style of your content, as well as the timeline, roles, and responsibilities of each party. You also need to discuss how you will measure and share the results of your content, such as traffic, leads, conversions, or engagement. Having a clear and mutual understanding of your goals will help you avoid confusion, conflict, and disappointment later on.
