Reach vs Impressions
Reach counts unique people who saw your content; impressions count total times your content was displayed.
Why It Matters
Confusing reach and impressions leads to misinterpreting campaign performance and making wrong budget decisions.
How It Works
Reach is always less than or equal to impressions because each person can generate multiple impressions. The ratio of impressions to reach tells you the average frequency at which your audience sees your content.
Real-World Example
An ad with 100,000 impressions and 40,000 reach has a frequency of 2.5, meaning each person saw it about 2-3 times.
Common Mistakes
Reporting impressions as reach to inflate perceived performance
Not calculating frequency to detect audience fatigue

Which metric should I report to stakeholders?
Report both: reach shows how many unique people you're hitting, impressions show total exposure, and frequency ties them together.
What is a healthy frequency?
