What are impressions?

The selected answer option is correct because impressions refer to the number of times an ad has been displayed on the search engine results page. An impression is counted each time an ad is shown, regardless of whether it is clicked or not. This metric is important because it measures the visibility of the ad, giving advertisers an indication of how often their ad is being served to users. Impressions are a key factor in understanding the reach of an ad campaign and how many people are potentially seeing the ad. Unlike clicks, which only occur when a user interacts with the ad, impressions represent the opportunity for engagement, and tracking them helps advertisers assess the effectiveness of their ad placements in terms of exposure.
