Longer video ads boost conversions by 50% over shorter ones

With the rise of TikTok, video has been all about the short format. But now new research from growth acceleration platform Liftoff finds that longer video ads are more effective than their shorter counterparts. Mobile user acquisition managers seem to be focusing on videos between 30 to 60 seconds in length for better performance gains.

Longer is better for video ads

Although attention spans may be short, slightly longer mobile video ads are proving effective in capturing user attention. Brands saw 50% higher conversions with longer videos than shorter ones. In part that’s due to longer video being able to more successfully tell stories.

Liftoff recommends mixing and matching existing ad materials to create longer video ads.

Marketers are advised to consider the motivations and ad preferences that can drive user engagement. These can be divided into escapism, social, mastery, management, expression, and exploration. Those who match player motivations and ad creatives are able to drive more growth. Motivations also enable marketers to pinpoint their audiences more successfully and capture attention more fully.
