Exclusion Audience is an audience removed from campaign eligibility to avoid wasted spend or irrelevant messaging.
It matters because most visitors do not convert on the first visit. Retargeting terminology helps teams create thoughtful follow-up sequences, avoid wasted impressions, and respect audience exclusions and privacy expectations.
Example
A recruitment campaign can exclude current employees where the platform and data setup support it. The exclusion narrows campaign eligibility; it is not a guarantee that every employee will be recognized or excluded on every device.
