Metrics such as the number of impressions served, how many unique customers were reached, and the click-through rate are related to which stage of the customer shopping journey?

Explanation:

The correct answer is **Awareness**, as metrics such as the number of impressions served, the count of unique customers reached, and the click-through rate are essential indicators of how effectively an advertising campaign is generating visibility and recognition for a brand or product. During the awareness stage of the customer shopping journey, the primary goal is to reach and inform potential customers, and these metrics help assess the campaign’s reach and initial engagement. By analyzing these figures, advertisers can determine how well they are capturing the attention of their target audience, laying the groundwork for subsequent stages of the shopping journey, such as consideration and conversion.
