An editorial calendar is used by bloggers, publishers, businesses, and groups to control publication of content across different media, for example, newspaper, magazine, blog, email newsletters, and social media outlets.
At Media Junkies, we map out the content for the upcoming 30 days, send it to our clients for review and publish after approval to the respective channels. We normally follow a routine of different content forms and types (e.g. Mondays an inspirational post, Tuesdays an industry article, etc.). Here is an example of an editorial calendar:
We are using a slightly different format For Instagram, Pinterest and tumblr as we are working mainly with imagery here. The images will be sent to our clients via a dropbox link for review. Here is an example of an Instagram editorial calendar.
