According to LinkedIn, anyone who watches at least 50% of your video ad is ready to be retargeted.

This statement is false. While watching 50% of a video ad indicates significant engagement, LinkedIn's official guidance suggests a higher threshold for optimal retargeting. LinkedIn recommends retargeting audiences who have watched 75% or more of your video ad. This higher completion rate typically signifies a stronger interest in your content and a greater likelihood of conversion, making them a more qualified audience for subsequent retargeting efforts. Retargeting based on only 50% viewership might include individuals with casual interest who are less likely to convert.
