Content marketing requires manpower, so the first step is figuring out who is going to head up the program. There's no one-size-fits-all for team structure -- it depends largely on the size of your company, your marketing team, and your budget. But if we assume that those three things are interlinked, as they often are, I can provide you with some frameworks based off of other content marketing-focused companies' structures. These should help you hire the right people, and have them "sitting" in the right spot in your organization.
Bloggers are people who make dumb list articles with sensationalized titles to try to garner search hits on their website, which in turn they hope will turn into clicks on ads so they can try to make money. Bloggers also write very one-sided articles, which tend to either evoke extreme praise for the article or extreme flame wars. There is rarely any middle ground.
Let's say you're using PPC as your primary means of generating leads for your business. You need more leads, and decide to bid on the term "infographic generator" for $2 a click. At the end of your month-long campaign, you generated 1,000 leads and spent $10,000. Not bad. But what about next month? You have to spend $10,000 again. And again. And again. That is, if you want the leads to keep coming. In other words, when you turn the faucet of money off, leads stop coming out. The same concept applies with list purchasing, tradeshow marketing -- anything where you don't own the property from which leads are generated. Now let's contrast that experience against, say, blogging.
While successful content writers seem to have an enviable life -- they work from home, make their own schedules and work as much or as little as they please -- the vast majority have a hard time making a living of it. They lack the skills necessary to succeed. Because no matter how talented they are, writing skill is simply not enough. So, if you want to become successful as a content writer, you need a full toolkit of marketable skills.
