An advertiser wants to measure how many people bought a product after seeing a Facebook ad, even if they never clicked the ad. What must be in place to capture this data?

View-through measurement requires Campaign Manager 360 to record an impression before a later Floodlight conversion occurs. For paid social inventory that is not directly served by Campaign Manager 360, an impression-tracking setup records the ad exposure without requiring a click. That exposure can then be matched to a purchase within the configured conversion window. A click-only setup would exclude users who viewed the ad but never clicked.
