The Placement Format specifies how this placement area will behave:

• Random List Adverts are display in a completely random order ignoring their group.
• Grouped - Random Adverts are display with items from the same group in a block. But within each group the individual adverts are displayed in a random order.
• Grouped - Alhpa Adverts are displayed sorted in order first by group and then alphabetically within that group based on the advert title
