Reach vs impressions definition: a quick example#
A post seen twice by the same person adds 1 to reach and 2 to impressions — the gap between the two numbers is exactly that repeat-viewing effect, which is why a widening gap over time usually means the same audience is seeing a post more than once rather than the audience growing.
FAQ
- Which metric matters more, reach or impressions?
- It depends on the goal — reach is closer to "how many different people did this touch," impressions is closer to "how much total exposure did this get," including repeat views. Neither is strictly better; they answer different questions.
