What it means

An ad impression is a single display instance of an ad on a screen, counted each time the ad loads and is served to a user, regardless of whether it’s clicked.

Impressions are the foundation metric behind CPM, reach, and frequency — without counting them accurately, none of those higher-level metrics can be trusted.

The base unit of measurement

Nearly every other visibility metric is derived from impression counts.

Confirms delivery

Impression data confirms your ads are actually being served where and when planned.

Enables CPM pricing

Impressions are what CPM campaigns are bought and billed against.
