Impression class

A type of event that contains details about activities a user has viewed.

Tracking impressions allows you to know what activities have been shown to a user and learn what specific users are or are not not interested in.

For example, if an app often shows posts about football and the user never engages with those posts, we can conclude that we're displaying the wrong content to that user.
