Just recently I hosted a community play stream and a very interested topic was brought up in regards to marketing, specifically how to market a fortnite creative or UEFN map. A great resource I always share with others when this is brought up is the Fortnite Creative Marketing Playbook. This resource is packed with helpful guides and tips on how to initiate marketing for your map. There is even a full fledged FNC Marketing Plan PDF guide help you plan it out your goals step by step. It is so beneficial! 
After a few conversations had set forth, I realized that it could be even more helpful to share that you could take the information placed into the FNC Marketing Plan and create a Marketing Action Plan, all complete with Goals and Tasks to help ensure you reach those goals.
So I created an article showing you how to create a Marketing action plan just like this.
Inside you can discover more such as: what is a marketing plan and how you can create your own action plan from set goals.

I also included an example spreadsheet template that can be saved to your google spreadsheet folder and then easily exported into Notion or Asana. This way you can easily customize it for your needs.
