Impressions
An impression is counted every time a piece of content is rendered on a viewer's screen, regardless of whether they engage with it.
An impression is counted every time content appears on a viewer's screen. Unlike reach, impressions can count the same viewer more than once — if a post shows up twice in the same user's feed, that is two impressions but one person reached.
Impressions are the volume metric. They tell you how much raw surface area your content occupied. They do not tell you whether anyone read it, watched past the first frame, or took action.
Platforms report impressions differently:
- X and LinkedIn expose impressions per post in creator analytics.
- Instagram calls them "views" on most surfaces and "impressions" inside professional dashboards.
- TikTok does not publish impressions — it reports views, which use a lower threshold.
Use impressions as the numerator in reach rate and engagement rate denominators.
