Every marketer wants a framework for their marketing strategy. And in planning your social and content marketing strategy, what's the right mix of first-party and third-party content? How often should you post purely promotional messages? While plenty of people will tell you that it "depends," we're willing to commit to a specific ratio: 30/ 60/ 10. It's how we run our social media and content marketing, and we think it's a good way for you to run yours as well.
