Some publishers choose to sell their inventory by the number of ad impressions. This creates a question of exactly how quickly those impressions should be delivered, commonly referred to as “campaign pacing” or “impression pacing.” Impression pacing is only possible when there is both an impression limit and end date set for the campaign.
Broadstreet offers two types of pacing:
ASAP: This type of pacing delivers campaigns advertisements as fast as possible. For example, let’s say you create a campaign with an end date 3 months from today, and you set an impression cap of 100,000. If you received a few hundred thousand page views within that first week, the ad server will deliver that campaign and exhaust the impression cap as quickly as possible. It’s possible that the campaign will essentially end well before its stated end date.
EVEN: This type of pacing spreads impressions out over the course of the campaign. Broadstreet does this by intelligently creating a schedule for impression delivery and periodically adjusting it to come as close as possible to a perfect pace.
For EVEN pacing, it’s expected that the ad units (zones) that the campaign has placements in have the collective traffic required to deliver the expected impression maximum for the campaign. Campaigns that are under-delivering due to insufficient volume and share of voice scenarios may have their weights manually adjusted in the campaign settings as well. Broadstreet does not automatically adjust campaign weights in an attempt to achieve perfect delivery since it may interfere with obligations for other campaigns.
You can edit the impression pacing under the flight tab inside the campaign.
