  • placement is a group of ad unit
  • ad unit represents an ad location (ie where ad content can go)
  • key-values provide horizontal targeting (e.g., team=yankees, gender=female). Doc

Hierarchy

Ad units have a “parent-child” relationship, meaning that ads targeting the top-level ad unit (the parent) can also target the lower-level ad units (the children).

The hierarchy should mirror the organization of the site’s content.

Example:

  • Sport (Parent)
    • Tennis (Children)
    • Football (Children)
    • Baseball (Children)

A ad for sport can be shown on the children
