Ad Impression (Single Ad View)
One single instance of your ad appearing on a screen — the basic unit that all reach and visibility metrics are built from.
…Delivery reports will track total ad impression volume alongside clicks so you can see the full funnel, not just the clicks.…
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.
DNA's Take: We report impression volume alongside engagement metrics so clients can see the full picture — how many people saw the message, not just how many clicked it.
