For brand safety, you may not want to be associated with particular sites or apps that are controversial or espouse values at odds with your brand values. You can leverage block and allow lists when delivery (or non-delivery) on specific sites is critical to the campaign. We recommend using site lists sparingly, however, as they may adversely impact reach and performance. The Quantcast Platform supports two types of lists: 1. **Allowlist**: The system will only consider bid opportunities from apps and domains on this list. 2. **Blocklist**: The system will ignore bid opportunities from apps and domains on this list. Here is how to set up site lists for brand safety: 1. From the **Assets** section in the top navigation menu, select **Inventory**. ![](https://cdn.us.document360.io/9a180fa0-df3b-4942-a5f6-b3905cf917d9/Images/Documentation/Assets_from_menu.png?sv=2026-02-06&spr=https&st=2026-11-08T07%3A15%3A41Z&se=2026-11-08T08%3A15%3A41Z&sr=c&sp=r&sig=LMF6rkxkI7Q4HeymfANhAZSGbONg%2BQmAeeQ3tCdZ26s%3D) 1.

You can add apps or domains manually or import a pre-defined list. - For Apps - Each item should be an app ID. - Each item should be on a new line. - You can include up to 100,000 lines. - File size cannot exceed 700kB. - App ID entries should not include the app store link. For instance, use "com.discovery.discoverygo" instead of "https://play.google.com/store/apps/details?id=com.discovery.discoverygo&hl=en_US&gl=US" - App ID should not include the app name. For instance, use "com.discovery.discoverygo" instead of "Discovery GO" - For Domains - Each item should be on a new line. - You can include up to 100,000 lines. - File size cannot exceed 700kB. - *URLs should not include “www.” For instance, use “nytimes.com” instead of “www.nytimes.com”*. 6.
