Advertiser Domain Deduplication checks are case-sensitive.
We compare only the top-level domains during this check. So, as an example, the domains https://espn.com and https://espn.com/soccer/world-cup/schedules.html will be treated the same and this will fail the advertiser domain deduplication check in the AdServer.
Demand tags with no advertiser domain will be excluded from this deduplication check and always included in the pod.
In the SpringServe UI, clients have the ability to set advertiser domains on the Demand Partner and the campaign.
If this is set, we check for dupes on the DP and campaign advertiser domain on all the demand tags in the lower slots of the pod whether they belong to that campaign/demand partner or not.
