According to LinkedIn, objective-based optimization is activated when you focus on maximum delivery and select reach or video views as an optimization goal.

This statement is true. LinkedIn's advertising platform uses objective-based optimization to help advertisers achieve their campaign goals. When you choose "maximum delivery" as your optimization strategy and select specific objectives like "reach" or "video views," LinkedIn's algorithms will prioritize showing your ads to as many relevant users as possible or maximizing the number of video plays, respectively. This approach ensures that the campaign is automatically optimized to perform best against the chosen objective, making efficient use of the budget to achieve the desired outcome. Other objectives, such as website visits or lead generation, would trigger different optimization behaviors.
