Reach vs Impressions: Key Differences and Why They Matter

Reach measures unique people who saw your content, while impressions count total content views including multiple views by the same person. Both metrics provide different insights into your social media performance.

What Is Reach?

What Are Impressions?

Impressions count every time your content appears on someone's screen, including multiple views by the same person.

Key Characteristics of Impressions
