Most online marketers agree that an editorial calendar is a must for any organization that's serious about content marketing. I'm going to take that a step further and say just having a spreadsheet, or using Google Calendar, or some other tool that isn't designed specifically to be an editorial calendar puts your brand, and your marketing at a disadvantage. My editorial calendar is the only tool that stresses me out when I don't look at it for more than a day, and the only tool that gives me that zen feeling about the content marketing pipeline for my company and our clients. When we were was using static tools a few years ago I had all of the stress and none of the zen. There are lots of options out there from CoSchedule to ContentDJ and others. We use, recommend, and love DivvyHQ. We put together this infographic to show how an editorial calendar app provides insights and capabilities that make it an indispensable tool for serious content marketers.
