What is a Reach?
The number of unique users who saw your ad or content.
Understanding Reach
Reach measures the number of unique users who saw your ad or content at least once. Unlike impressions (which count every view), reach counts each user only once regardless of how many times they saw your content.
Reach is essential for brand awareness campaigns where the goal is exposing as many different people as possible to your message. The relationship between reach and impressions reveals frequency—how many times the average user saw your content. While high reach is valuable, you also need sufficient frequency for message retention. Most experts recommend 3-7 exposures for brand recall. Balance reach and frequency based on your campaign objective—awareness campaigns prioritize reach, while conversion campaigns may benefit from higher frequency.

Reach measures the number of unique users who saw your ad or content at least once. Unlike impressions (which count every view), reach counts each user only once regardless of how many times they saw your content.
Why is Reach important?
Reach indicates the breadth of your audience exposure—how many unique people you're actually reaching versus repeatedly showing ads to the same small group. For brand awareness, reach is often more important than impressions because exposing 100,000 people once is usually more valuable than exposing 10,000 people 10 times. Understanding the reach vs. impression ratio reveals whether you're achieving efficient audience coverage or burning budget on excessive frequency.
