When you create a campaign, use the Inventory tab to control where your impressions can appear. In this tab, you can:
- Select exchanges, domains & apps, and domain lists
- Set exchange bid multipliers
- Select supply path optimization settings
In the Inventory tab, click Select Inventory. You can then set up the exchanges, domains & apps, and any domain lists you want to use.
By default, your campaign bids on impressions from all exchanges. You can also choose specific exchanges that you want to use by clicking Select exchanges and checking exchanges in the list.
Click Next to move to the Domains & Apps tab.
Domains & Apps
By default, your campaign bids on impressions from all domains and mobile apps. You can also choose specific domains and apps to target Select domains & apps and checking them in the list.
Click the arrow next to the domain or app name to select it on specific exchanges only. For example, the campaign will target yahoo.com, ebay.com, and mail.yahoo.com on any exchange chosen on the Exchanges tab, but it will target dailymail.co.uk only through PubMatic.
Filters help you find the domains and apps you're looking for in this very long list. See Available Inventory for more information.
Click Next to move to the Domain List tab.
If you want to further control your inventory with a domain list (either an allowlist or a blocklist), select it in the Domain List tab. See Domain Lists, Using Allowlists and Blocklists and Domain Lists for Mobile Apps for more details.
You can increase or decrease the bid amount for different exchanges in this tab as well. For more information and instructions, see Bid Multipliers.
Basis DSP provides options to help you avoid ad fraud and have greater control over the inventory that your campaign targets, including more integrations, fewer duplicate impressions, and more direct traffic.
Under Supply Path Optimization, select any of these three options:
- Exclude sites and apps without Ads.txt
- Exclude site and apps that do not participate in Ads.txt. By default, campaigns bid on authorized supply paths for sites and apps that do participate in Ads.txt, as well as those that do not participate in Ads.txt.
- Target direct publisher relationships only
- Only bid on bid requests where a SupplyChain object is present, marked as complete, and contains no more than one hop. By default, campaigns target inventory with no restrictions on the number of hops and the completeness of the supply chain.
- Opt out of Supply Quality filtering
- Opt the campaign out of the DSP's default supply quality filtering. This may expose your campaign to low quality supply paths and is not recommended.
