Goal-Based Bidding

Bidding optimized toward a specific action you name, so Snap buys the impressions most likely to produce that action.

You set the goal, a purchase, an install, a lead, a swipe, and Snap's delivery optimizes bids to get that event rather than raw clicks or impressions. It uses your pixel or app signals to decide who is likely to complete the action and bids for those people. The goal you pick reshapes who the ad set even tries to reach.

You optimize an ad set for purchases instead of link swipes. Snap stops chasing cheap swipes from browsers and starts spending on users its model reads as likely buyers, so swipe volume may drop while actual sales rise. The cheaper-looking metric gets worse and the one that pays your bills gets better.

You cannot optimize toward an event Snap barely sees. Pick a goal that fires only a handful of times a week and the system never gets enough signal to learn, so it delivers erratically. If purchases are too rare, optimize for a reliable upper-funnel event first and move down once volume supports it.

Optimize for the outcome you bill on, once it fires often enough to learn from.
