With the default Best position label placement option, labels can be placed in any of eight zones around a point. For cartographic consistency, the Maplex Label Engine first tries to place each label to the northeast of the feature. If the label can't be placed there, it tries the north and east zones, and then works its way around the zones until the label is placed. You can control the order in which the Maplex Label Engine tries the zones.
If you are using the Best position label placement option, you can set the preferred zones for placement under the Placement expander.
The Maplex Label Engine attempts to place each feature's label in each zone in the order you specify. You control the search order by ranking the zones on a scale of 1 to 8, where 1 is the first zone in which you want it to try to place the label and 8 is the last zone. You can give a zone the value 0 to prohibit labels from being placed in it. While multiple zones may be blocked with 0 ranks, the other zones must have unique ranks. When the Maplex Label Engine starts to place the labels, it evaluates the blocked zones and the amount of congestion around the point feature, considers the location of other features and other labels, and places the label in the best available zone.
