Digital marketing term
Reach
Reach is a core visibility metric that counts the number of unique users who saw a piece of content or an ad at least once within a given period.
Detailed explanation
While impressions count total views, this metric counts a user who saw something multiple times only once; that makes it a more accurate indicator of how many different people a campaign actually reached.
This value is read alongside frequency; dividing total impressions by reach gives the average number of repeat views, which helps assess ad fatigue risk.
In brand awareness campaigns, this metric is typically used as the primary success indicator, while in performance campaigns it's tracked as a secondary, contextual metric.
