Google Ads has introduced a warning in Demand Gen campaigns, notifying users when their video assets are shorter than 10 seconds. These shorter videos are ineligible for in-stream placements, limiting campaign reach and performance.

To ensure full coverage, it’s recommended working video assets longer than 15 seconds that are eligible across Demand Gen, Video, and Performance Max. This avoids placement limitations and improves campaign flexibility.
The update was shared by Arpan Banerjee and Adriaan Dekker.
