What this question tests
Working knowledge of video ad metrics and the ability to connect them to advertiser and platform goals.
How to approach it
- Clarify whose success is being measured, the advertiser's or the platform's, since the metric set differs.
- Start with delivery and viewability metrics: impressions, viewability rate, and completion rate.
- Add engagement metrics: click-through rate, and for skippable ads, view-through rate before skip.
- Include outcome metrics advertisers care about: conversion rate and cost per acquisition where trackable.
- Add platform health metrics: ad load time, and fill rate, since a slow or unfilled ad hurts revenue and user experience.
- Tie the metrics together into a simple funnel, from delivered to viewed to engaged to converted.
What a strong answer includes
- Names completion rate and viewable impressions as the two most load-bearing metrics for video specifically, since video ads are judged on attention, not just delivery.
- Gives an illustrative benchmark as an assumption, for example a 70 percent completion rate for a 15 second pre-roll being considered healthy.
- Explains why click-through rate is weaker for video, since many video ads aim for brand awareness, not direct response.
- Connects platform-side metrics, like fill rate and latency, to advertiser trust and repeat spend.
Common mistakes
- Listing only click-through rate and impressions, ignoring completion and viewability which matter more for video.
- Not separating advertiser-facing metrics from platform health metrics.
- Failing to mention viewability standards at all.
Likely follow-up questions
- How would you define viewability for video specifically versus display ads?
- Which of these metrics would you prioritize if you had to pick one north star?
