In social media terminology, "impressions" refer to the number of times a piece of content (such as a post, photo, video, or advertisement) is displayed on users' screens. This metric counts each time the content appears, regardless of whether users actually engage with it (such as clicking, liking, or commenting).
Impressions help measure the reach and visibility of a post, campaign, or brand on social media platforms. It's important to note that impressions do not indicate how many unique users saw the content; one user can generate multiple impressions if they see the post multiple times. In summary, impressions are a key metric for understanding the general exposure of content in the social media landscape.
