Final answer:
The correct answer is option a) Impressions Impressions is the metric that measures the number of times an ad is served and is the correct answer for a video campaign with an awareness goal.
Step-by-step explanation:
. Impressions measure the number of times an ad is served to a user across various devices and formats. This metric is crucial for a video campaign with an awareness goal, as it reflects the ad's reach and how often potential customers are exposed to the campaign's message. While other metrics like click-through rate (CTR), conversion rate, and cost per click (CPC) are important for understanding user interaction and the cost-effectiveness of the campaign, they do not provide information on the total exposure of the ads.
Impressions measure how many times an ad is served to viewers. In a video campaign with an awareness goal, the primary objective is to reach as many people as possible to create brand awareness. By tracking impressions, you can determine the number of times your ads have been displayed across different devices and formats, such as mobile, desktop, or tablet, and different ad formats like in-stream or display ads.
