Reach vs Impressions: What’s the Difference?

Understanding the difference between Reach and Impressions is essential for measuring the success of digital marketing campaigns. While both metrics indicate content visibility, they measure different aspects of audience exposure.

• Reach = The number of unique people who see your content.
• Impressions = The total number of times your content is displayed, including multiple views by the same person.

For example, if 100 people see your post and each person views it 3 times, your reach is 100, while your impressions are 300.
