Pacing is the speed or rate at which an ad campaign uses up its predefined number of impressions or spends its predefined budget during its run-time. Advertisers can choose from various types of pacing, which will tell the ad server how to spread out the delivery of ads – including ASAP, back-loaded, even, front and back-loaded, front-loaded, and mid-loaded. See separate definitions for these different types.
