Promotion -- it's always been my weak suit. I can come up with ideas and churn out 10k words of content a day, but when it comes to driving traffic to that content, I've always been short on ideas. I don't think targeting an audience has really been an issue for me, but getting that audience to consume the content so I get feedback hasn't really been there, either. In niches I'm part of the target market in, or have been in the past, it's easy to pinpoint who I'm writing for. In unfamiliar niches, if I had traffic going to the content, I'm positive I could tweak and adjust to what they're wanting to see.
