Which metric is NOT listed among the core metrics for evaluating social media campaigns across platforms?

• A. Reach
• B. Impressions
• C. Engagement rate
• D. Video completion rate

Answer: (D)

Across platforms, evaluating social media campaigns focuses on exposure and how people interact with content. Reach shows how many unique people saw the content, giving a sense of audience size. Impressions count every time the content appeared in feeds, which helps gauge overall visibility. Engagement rate captures how actively the audience interacted, typically relative to reach or impressions. Video completion rate, on the other hand, is specific to video content, measuring what percentage of viewers watched the video to the end. Because it depends on video assets and doesn’t apply equally to non-video posts, it isn’t considered a cross-platform core metric. So it’s the best answer.
