What are impressions?

Question

Accepted Answer

Impressions count every time a piece of content was displayed, including repeat views by the same person. Reach counts people; impressions count appearances, so impressions are always the bigger number. The gap between the two is itself informative. High impressions against modest reach means people came back to it, which usually means it was saved, shared or rewatched, and that is a better sign than either number alone.
