Blacklist

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: Publisher IDs help identify specific apps, websites, or ad placements responsible for serving traffic. By analyzing performance metrics such as unusually high click-through rates, low conversion rates, or repeated fraud signals, marketers can flag publishers distributing low-quality or harmful ad inventory. Blocking these sources prevents ads from appearing in unsafe environments and protects overall campaign integrity.
  
  
• Device IDs: Device IDs make it possible to track activity at the individual device level. When the same device repeatedly generates fake installs, abnormal engagement, or suspicious post-install behavior, it becomes a strong indicator of fraudulent activity. Filtering such devices helps reduce invalid installs, improves attribution accuracy, and ensures marketing spend reaches genuine users.

• User Behaviors: Behavioral patterns provide valuable signals for detecting fraud. Repetitive clicks, rapid installs, zero engagement sessions, or unrealistic interaction speeds often indicate automated or manipulated activity. Monitoring these behaviors allows marketers to identify non-genuine interactions early and prevent campaign data from being skewed by misleading performance signals.
  
  
• IP Addresses: IP address analysis helps uncover networks linked to suspicious activity, such as click farms, data centers, or proxy networks. When multiple fraudulent actions originate from the same IP range, blocking them can significantly reduce fake traffic. This approach also helps prevent abuse from VPNs and anonymized sources that hide true user identity.
  
  
• Geographic Locations: Geographic data helps identify regions with consistently high fraud rates or abnormal traffic patterns. If installs or clicks from certain locations show low retention, zero conversions, or repeated fraud indicators, marketers can restrict exposure from those regions. This ensures ad spend is focused on locations that deliver real value and sustainable growth.
  
  

When a blacklisted entity tries to interact with an app or advertising campaign, the system automatically blocks their access or engagement.

Types of Blacklists in Mobile Marketing

Publisher Blacklisting

If an ad platform or app publisher is known for hosting spammy or fraudulent ads, they can be blacklisted. This helps make sure advertisements do not run on unsafe sites, maintains high campaign performance, and strong brand image.

• Blacklists unreliable publishers or ad networks.
• Prevents the ads from appearing where they are not wanted and minimizes exposure to fake or useless traffic.

Device Blacklisting

The campaigns are protected by blacklists that target devices used for suspicious activities such as fake app installs or click injection.

• Filters traffic coming from infected devices from accessing the network.
• Improves ROI by detecting and reducing invalid installs and actions.

IP Address Blacklisting

Most of the activities that involve fraud such as bot traffic are usually originated from a certain IP address. By identifying and blacklisting these, marketers can be assured of the quality of traffic.

• Blocks the IPs of the bots or fake clicks..
• Prevents from VPNs or proxy abuse.

Geographic Blacklisting

In regions with high fraud rates, marketers can save their budget by simply blacklisting traffic from those particular areas.

• Ensures ad spend is allocated to quality traffic.
• Reduces exposure to areas that are susceptible to fraud issues.
  
  

How Do Blacklists Work in Mobile Marketing?
