What are Blacklists?
In mobile marketing, a blacklist is a database or list that comprises identified sources of the suspicious and the fraudulent. These sources could include:
- Publisher IDs: Helps identify platforms distributing low-quality or harmful ad inventory.
- Device IDs: Can reveal individual gadgets that generate fake installs or exhibit destructive behavior.
- User Behaviors: User behavior patterns like repetitive clicks or installs serve as important indicators of potentially fraudulent activity.
- IP Addresses: May indicate networks harboring bot traffic or click farms.
- Geographic Locations: Its data can highlight regions where ad fraud commonly occurs.
When a blacklisted entity tries to interact with an app or advertising campaign, the system automatically blocks their access or engagement.
