This part of the research as to look at the way text, images, fonts and different layouts work together and to get knowledge of what works and what doesn't.
Every time I viewed a magazine layout I scanned it for information on how, why and when a layout was layed out in that particular fashion. Some times I'd find out that certain double page spreads were placed together purely because they were the last ones left. often enough you fund articles and adverts next to each other and at least some times you can tell that product placement has been used.
