It is important to think about the magazine titles you place next to each other from the perspective of those who purchase the titles. For example, Super Food Ideas and Feast appeal to quite different shoppers. One is a supermarket type food magazine aimed at budget family cooking while the other is a title for lovers of quality food and the food journey. I don’t think that they sit well next to each other. By that I mean that there are other titles would work better next to each than having these two titles together.
Adjacencies are all about driving the additional purchase. This is why we try and place titles next to each other which are likely to appeal to the same shopper.
