Targeting settings in Pontiac can be applied at either the Campaign level and/or the Line level. Understanding how these interact is key to ensuring your impressions remain eligible.

The Intersection Rule

• Campaign level targeting acts as a global filter for all line items under that campaign.
• Line level targeting applies only to the specific line.
• When targeting is applied at both levels, the effective targeting is the intersection of the two:
  • Effective Targeting = Campaign Targeting ∩ Line Targeting
• This means an impression must satisfy all conditions applied at both levels in order to be eligible.
  

Best Practices

• Use campaign level targeting when the parameter applies universally to all lines (e.g., every line must serve only in the US).
• Use line level targeting when the parameter is unique to a strategy (e.g., one line targets ZIPs in California, another in New York).
• Apply settings at one level only whenever possible, unless the intent is to explicitly restrict eligible inventory via intersection.
