Ad Impression
A metric used to quantify the number of times an advertisement is fetched and displayed on a screen.
An Ad Impression occurs every time an ad is successfully fetched from its source and displayed to a user. It does not necessarily mean the user clicked on it, or even looked at it, but rather that it was loaded on the page.
Impressions vs. Reach
While impressions count the total number of times an ad was shown, reach counts the number of unique people who saw it. If one person sees the same ad 3 times, that counts as 3 impressions but a reach of 1.
Why tracking impressions is vital
