Content marketing is a long-term strategy and an editorial calendar helps you plan your strategy in an organized fashion. The calendar will contain details such as −
List of the kinds of content you have or need to create, including the dates when they will be created and published
The names of the content editors/producers and other stakeholders who are responsible for the project
The media channel that you will use to market your content
Metadata such as your primary target audience, SEO keywords, call to action, etc.
While you can use a simple tool such as an Excel or Google sheet to create an editorial calendar, you can also use web-based software offered by companies such as HubSpot, Skyword, etc.
