It's a set of 4 organizational types profiles that'll help you rule out pieces of advice that will NEVER work for you and save you a lot of time. The site and that lady's books will have some advice tailored to the profile you match. Like, I'm a Butterfly which means that closed closets and cabinets and opaque storage boxes don't work for me, I have to have everything out and visible to organize it and remember it's there. So I focus on advice about that, like hanging things from the wall and open shelving. Other people, though, just consider that visual stress.
