App Store impressions
What Apple counts as an impression, where the metric appears, and what it cannot prove.
In brief
An App Store impression is counted when an app is viewed on the Today, Games, Apps, or Search tabs for more than one second. Apple includes product page views in the total.
The platform definition
Apple defines Impressions as the number of times an app was viewed on App Store discovery surfaces for more than one second. Unique Device Impressions deduplicate those views by device.
The common misread
Impressions are exposure, not necessarily intentional consideration. Search, Browse, featuring, ads, and repeated exposure can represent very different levels of intent.
The decision it can support
Use impressions to locate changes in visibility and to compare source mix. Do not use them alone to judge listing quality or product-market fit.
Read the number with territory, device, source, product version, and enough time context. A metric can describe an outcome without identifying its cause.
Primary sources
Rules and interfaces move. Recheck these sources before submission-sensitive work.
