Reach vs. Impressions
Reach is the number of unique users who saw your content; impressions is the total number of times it was displayed.
Full definition
Reach and impressions are related but distinct metrics. Reach counts the number of unique people who saw your content at least once. Impressions counts the total number of times your content was displayed, including multiple views by the same person. If 1,000 unique users each saw your post twice, reach = 1,000, impressions = 2,000. Frequency (Impressions ÷ Reach) tells you the average number of times each person has seen your content — important for ad fatigue management. For brand awareness, maximising reach is the goal. For retargeting or frequency-dependent campaigns (e.g. direct response), managing impressions and frequency is critical.
Real-world example
A brand awareness campaign reaches 450,000 unique users with 1.3M impressions (frequency 2.9). The brand tracking survey shows a 15% increase in unaided awareness.
