Here is something White Hat, but with great Black Hat possibilities. Definitely BS possibilities.
It comes from Jay Abraham. He calls it the Amazon School of Copywriting. Basically, you seek the top 100 books in your field on Amazon. Choose an interesting one, then look at the reader reviews.
If you are BSing, you are seeking to fake empathy through proper polarization. In other words, there are "love it" reviews and "hate it" reviews. Since they come from the heart, they are really accurate for niche profiling.
Anyway, you draw a line down a blank sheet of paper, then take note of the positive points (benefits, features, opinions, solutions, etc.) on the left side and the negative points on the right side. When you write your copy or content, including articles, you refer to these points and use them to explain how your product (or point) will move the reader closer to what he wants, or will eliminate the things he doesn't from his life.
But Jay says it so much better... My stuff is BS next to his...
