Campaign Objective

A campaign objective is the goal you pick that tells Snapchat's auction which action to optimize toward.

You choose it when you create the campaign, and it shapes everything that follows. The objective decides which optimization goals and bid options you can set, and it tells the delivery system whose attention to buy. Pick awareness and Snapchat chases cheap reach. Pick sales and it chases people likely to buy.

Say you sell online but you choose the awareness objective because it shows the lowest cost per thousand. You get plenty of impressions and almost no purchases. Switch the same budget and creative to the sales objective and the system starts finding buyers instead of eyeballs, even though the cost per thousand looks higher.

The objective is not a label, it is an instruction to the algorithm. The most common waste on Snapchat is running a lower-funnel goal on an upper-funnel objective because the reach metrics look flattering. Cheap impressions that never convert are not cheap.

Optimize for the outcome you actually want, not the number that looks best.
