What does the term "impressions" refer to?

The term "impressions" specifically refers to the number of times an ad is displayed to users. This metric is crucial in measuring the visibility and reach of an advertising campaign. Each time an ad appears on a user's screen, whether or not they interact with it, it counts as one impression.

Understanding impressions is fundamental for evaluating the performance of an ad. A high number of impressions can indicate that the ad is visible to a large audience, which is essential for brand awareness. However, impressions alone do not provide insights into user engagement or the effectiveness of the ad in driving conversions.

Other terms in the context of digital advertising, such as clicks and revenue, serve different purposes. Clicks measure the interaction with the ad, revenue relates to the financial outcome of ads, and total spend indicates the budget used for the advertising efforts. Each of these metrics contributes to an overall understanding of campaign success but does not define impressions.
