Utilize categories to control advert automation
Places can have a set of categories, which are used to control the display candidates of a place. The main idea behind categories is that we sometimes want to display adverts at strategically good places. E.g. we might have a couple of posts about healthy food and the advert about a new kind of diet should be displayed there. This is achieved by inserting places at these posts and tag them with a category nutrition
. Then every advert with the same category is displayed there more likely. This also holds for adverts which are created in the future and tagged with the category nutrition
.
