Definition
Impression
An impression occurs when your app appears in an app store search result, browse section, or chart. Impressions measure your app's visibility before any user interaction.
Impressions represent the top of your app store funnel. Every time your app is shown to a user in search results, browse sections, or charts, it counts as an impression.
High impressions with low taps indicate a visibility problem — your icon, title, or ratings may not be compelling enough to stand out. Low impressions suggest you need to improve your keyword targeting to appear in more searches.
