Unique Reach: Definition

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). If someone sees your ad on their mobile device and then sees it again with another person on a connected TV (CTV) device, your ad will receive three impressions (co-viewed) and Unique Reach can tell you that those impressions came from two users.

Unique Reach metrics include:

  • Unique users
  • Avg. impr. freq. per user (frequency)
