Video and static display ads represent two different bets: video usually pays more per impression but costs more to produce and load, while display is cheaper and faster but earns less attention.
Revenue and engagement differences
Video ads, especially rewarded and interstitial video, typically post higher eCPM than static display formats of a comparable size, since advertisers generally pay a premium for the deeper engagement video creative can deliver. Static display ads load faster and use less bandwidth, which matters in markets with slower or metered connections.
Choosing based on connectivity and content
Apps targeting markets with strong, cheap connectivity can lean further into video without much downside; apps with a meaningful share of users on slower networks may see better overall performance from a display-first approach, occasionally supplemented with video in select placements.
