What is Impression?

Impressions are the number of times a particular advertisement is seen.

Definition

In marketing, impressions refer to the number of times an advertisement is seen by consumers. This metric is used to gauge the reach of an advertising campaign and to assess its effectiveness. Impressions can also be expressed as a raw number (e.g., the ad was seen by 10 million people). In either case, impression data can be used to compare different advertising campaigns and to determine which one is most effective at reaching its target audience.

While impressions are a valuable metric, they should be considered alongside other metrics, such as click-through rate (CTR), to get a comprehensive view of an advertising campaign's performance.
