Domain Lists

By default, a DSP tactic can bid on inventory on any domain or app that’s available for auction. You can limit a tactic’s scope to a set of domains by using a domain list.

Domain lists store domain names and apps that are exclusively targeted (on an allowlist) or blocked (on a blocklist) in your tactics. Domain lists can be shared by any of your tactics.

Allowlists and Blocklists

A domain list is either an allowlist or a blocklist, but not both.

When a tactic uses a domain list, it only bids on impressions where the domain name or app ID matches the rules set by the domain list:

  • Allowlist: bid on all impressions where the domain name or app ID/bundle ID is observed in the bid request.

  • Blocklist: never bid on impressions where the domain name or app ID/bundle ID is observed in the bid request.

Note: Blocklists can only block domains and apps when a domain, app ID, or bundle ID is declared by the exchange or publisher. If your tactic delivers to a blocklisted domain or app, the most likely reason is that the impression did not list any domain or app.

Working with Domain Lists

To open the Domain Lists page, where you can see and edit all of your domain lists, click DSP Actions next to your DSP line items and select Domain List.

Viewing Domain Lists

When you have many domain lists, the filter and search tools help you find the list you're looking for.

Filter Results

Domain List Details

Name

The domain list's name should be descriptive to help you find it when you want to use it in a tactic.

ID

A unique number assigned to the domain list.

Type

Either Allowlist or Blocklist: 

Allowlist  

the DSP bids on all impressions where the domain name or app ID/bundle ID is observed in the bid request.

Blocklist

the DSP never bids on impressions where the domain name or app ID/bundle ID is observed in the bid request.

Domain Count

The number of entries in the list.

Note: Blocklists can only block domains and apps when a domain, app ID, or bundle ID is declared by the exchange or publisher. If your campaign delivers to a blocklisted domain or app, the most likely reason is that the impression did not list any domain or app.

Creating a Domain List

On the Domain Lists page, click New domain list. See Creating a Domain List for details.

Every domain list can be used by any of your tactics.
