Introduction to App targeting
Use source app IDs to allow or block apps to bid on. To locate source app IDs, use Unity’s Report Builder to analyze the geo-level of each source your campaigns have reached. Pinpoint the best performing sources to allowlist, and the poorest performing sources to blocklist.
Note: Sources may only be identified by their abstracted IDs; Unity cannot give out source IDs for specific apps.
Important: Source app IDs are case-sensitive.
Allowlist
Adding Source App IDs to your allowlist restricts bidding to those specified apps. Note that limiting sources limits the scale of your campaign, so restricting your allowlist too much can negatively impact the campaign's performance.
Blocklist
Adding Source App IDs to your blocklist excludes those specified apps from receiving bids.
