Measures the total number of people who were shown an ad. These metrics go beyond basic cookie measurement to help you understand how many people saw your ad across different devices, formats, sites, apps, and networks.
For example, if someone sees your ad on their mobile, their desktop, and their tablet, your ad will receive three impressions but Unique Reach can tell you that each of those impressions came from a single user (your ad reached a single user three different times).
Unique reach metrics include:
- Unique users
- Avg. impressions per user (frequency)
