Question: A brand is running an in-stream video ad that includes a 300x250 display banner appearing next to the player. In the final report, the specialist notices the video has 50,000 starts, but the display banner only has 30,000 recorded impressions. Which specific metric should the specialist analyze to confirm how many times that specific display banner was rendered?
- Companion Views
- Video Progress Events
- Companion Clicks
- Video Midpoints
Explanation
The companion-specific view metric counts renders of companion creatives served alongside an in-stream video ad. A video start does not guarantee that the companion banner was also rendered by the player or publisher environment. Comparing this metric with video starts identifies whether the banner delivered at the same rate as the primary video asset. The difference can reflect player behavior, available companion slots, or publisher implementation.
Why the other options are incorrect
Video Progress Events measure video playback milestones, not companion banner rendering.
Companion Clicks measure clicks on companion creatives, not impressions.
Video Midpoints measure 50% video playback completion, not companion banner delivery.
