The goal set for an advertising campaign that determines how the platform optimizes delivery.
Campaign objective is the goal you set when creating an ad campaign. It tells the platform what outcome to optimize for — awareness, traffic, engagement, leads, or sales. Choosing the right objective is critical because it determines which users see your ads.
The platform's algorithm shows your ad to different types of users depending on the objective. A "Traffic" campaign targets clickers. A "Conversions" campaign targets buyers. Choosing wrong means reaching the wrong audience.
