What do media impressions indicate?

Media impressions specifically refer to the number of times an advertisement is displayed to users, regardless of whether or not they interact with it. This metric helps advertisers understand the reach of their campaigns and the overall visibility of the ad.

Impressions provide a foundational understanding of an ad's exposure in the marketplace, enabling advertisers to gauge how many times their messaging has potentially reached an audience. Unlike clicks, which indicate direct interaction, impressions focus solely on the instances of display, capturing the total count without implying any viewer engagement outcomes. Thus, option B accurately reflects the function of media impressions in marketing analytics.

Other metrics mentioned, such as total clicks, engagement rates, or duration spent on the ad, relate to user interaction and engagement with the advertisement rather than the mere frequency of its display. These elements provide different insights into campaign performance but do not specifically quantify impressions.
