What makes a content marketing plan successful? Over the 15 years I have been running content marketing programs for business to business companies, I have seen certain elements consistently throughout all successful b2b content marketing strategies and content marketing plans. Here, I share the 5 primary factors that make content marketing success and 5 secondary factors of successful content marketing programs. While I talk about business to business marketing, these factors are also consistent with business to consumer (B2C) and business to education (B2E) marketing.
