The central place for all your content ideas! Add a new idea by clicking the "+ New" button at the bottom of the table, or record it directly form your Content Hub, in the Brain Dump section. Once you have recorded your idea, select the platform(s) you want to publish it on. You can also keep track of your content's status here, although I much prefer using the Work in Progress view of the Content Hub. Open the idea card (hover over the idea and hit "Open") to add more details or start drafting your content directly within Notion.
Remember: Every piece of content you produce should have a goal: either help you build your brand, educate and entertain your audience, or promote your services or products. Make sure you have a balance of 80% educate and build and 20% promotion every week.
