Impressions vs Product Page Views

An impression is your app showing up — in a search result list, a category chart, a “you might also like” shelf. The user hasn’t necessarily read anything about your app.

A product page view is someone actually opening your listing to look at the icon, screenshots and description.

If impressions are high but page views are low, your search result presentation (icon, name, first screenshot) isn’t pulling people in. If page views are high but downloads are low, the listing itself isn’t closing.
