What are ad impressions?
Ad impressions are a metric used in digital advertising to count the number of times an ad has been seen.
Key to note: Ad impressions measure how many times an advertisement has been displayed, regardless of whether the ad was clicked.
Impressions and clicks should not be confused as they reflect different results.
Ad networks that report on impressions measure impressions by at least 1 pixel of the ad being in view for at least 1 second for display and 2 seconds for video ads.
This metric is used across paid media campaigns as a metric to measure often a campaign’s success in reach and the frequency of an ad campaign. It can also be leveraged to measure the success of a campaign as it is part of the volume to calculate the CTR of a digital marketing campaign.
