As you know, sponsorship and standard line items have high priorities than the price line items and so Google will prioritize sponsorship line items to ensure timely delivery of the campaign.
But you don’t want to recreate ad impressions via AXT when a direct advertiser won the impression. Because they expect you to not refresh their ads at all. In such cases, we can simply block the AXT for specific advertiser IDs/Order IDs.
The sponsorship line item will deliver and we won’t make any ad request for the unit afterward.
