What Is Impression?

An impression refers to each instance in which an ad, a piece of content or another element is seen by a user. It is used in digital marketing and advertising in particular to measure how often an ad is displayed on screen. Impressions are used together with clicks, conversions and other metrics to evaluate the effectiveness of an ad. An ad can have many impressions, but that does not mean it will receive clicks or engagement.
