Which item is a metric?

• A. Conversions
• B. Revenue
• C. ROAS
• D. Impressions

Answer: (D)

A metric is a quantifiable measure used to track performance. Impressions fit that definition because they are a straightforward count of how many times an ad or piece of content is shown to a user. It’s a pure exposure value that helps you gauge reach and frequency without tying the number to actions or revenue. In contrast, conversions measure completed actions, revenue captures money earned, and ROAS expresses how effectively ad spend translates into revenue—these are outcomes or efficiency metrics that depend on user behavior and monetization. So, impressions serve as the most basic, raw metric among the options.
