Line Item delivery can be controlled using a number of different pacing options. Pacing options are located on the campaign detail page just below the Run card and to the right of the Goal card.
Pacing can be set to deliver a campaign As Fast as Possible, Evenly, or to meet a Daily Goal.
Step 1: Choose which Type of Pacing you want to use for your line item.
As Fast as Possible - All line items default to As Fast as Possible. This means that ads will be served whenever a line items meets the requirements for delivery (based on its Priority, Fill Rate, CPM, Geography, etc.), as the system works to meet the line item's Goal as quickly as possible. A line item set to As Fast as Possible may meet its Goal before the Run time is complete.
Evenly - Ad delivery will change dynamically throughout the entire duration of the line item to deliver as evenly as possible until it meets the Goal. A line item's delivery will be reduced if it is pacing ahead of schedule, and will be increased if it is pacing behind.
Daily Goal - Daily Pacing can be set to deliver “As Fast as Possible” or “Evenly” to meet the Daily Goal.
- Daily: As Fast as Possible - This setting allows the line item to deliver as it normally would, taking into account priority, fill rate, and CPM, but line item delivery will stop for the day when it reaches the number of impressions in the Daily Goal.
- Daily: Evenly - Ad delivery will be throttled or accelerated dynamically to meet daily impression goals while delivering as evenly as possible throughout the day.
Step 2: Set a Goal.
A Goal tells the system how quickly it needs to deliver a line item. A Line Item Goal can be based on Impressions or Spend and is set on the Goal Card located next to the Pacing Card.
If using a Daily Goal for Pacing, you will need to set a specific Daily Goal in addition to your Line Item Goal. A Daily Goal is based on Impressions and is set when you select Daily Goal on the Pacing Card.
Make sure that you set the Daily Goal high enough that it will meet the total Line Item Goal when multiplied by the number of days in the Run. When the Daily Goal is too small to reach the total Impression or Spend Goal for a line item, a warning message will appear.
