Ok, let me back up for just a minute. You don't really want to forget about SEO and keywords altogether. I'd be foolish if I acted like they have no place in your content strategy. But that's not where your strategy needs to start.
Do you feel weird about having someone write for you? Would you be surprised to hear that a large amount of the things that you read online aren't written by the person that is listed as the author? That's right. How do I know that? Because ghostwriting is one of the main things that I do for my clients.
