Inventory Quality

The Inventory Quality section of the RTB-Stack platform assists users in managing various types of lists to ensure cleaner ad traffic. Currently, this includes Pre-bid blocking lists. Pixalate, a leading traffic quality vendor, supplies our platform with regularly updated lists of suspicious traffic sources. This integration is crucial for effectively blocking potentially fraudulent or low-quality traffic, ensuring that our users benefit from cleaner and more reliable ad inventory.

Pre-bid Blocking Lists

To access the Pre-bid Blocking Lists tab, ensure you activate the corresponding module via the platform settings.

In the Pre-bid Blocking Lists table, you can view and manage various types of block lists. The table displays three main columns:

• Name: Lists the type of block list (e.g., Device ID, IPv4, OTT Block list).
• Last Update: Shows when the block list was last modified.
• Status: Indicates if the list is Active or Paused.

On the right, there are quick action icons for editing or pausing/activating the block lists for connected SSPs. Additionally, a search bar is available for easy filtering of lists.

Manage Pre-bid Blocking List Settings

The Edit List Settings modal window allows users to connect SSPs to blocking lists and add exceptions as needed. To access this window, users can either select a list from the table or use the 'Edit' button. The key elements of this modal include:

• Probability Threshold: Choose a probability threshold value from a dropdown list (values range from 0.5 to 1, in increments of 0.5). We recommend the following thresholds:

  1. 0.50–0.70: To filter out entities more likely than not to be fraudulent (preponderance of the evidence standard).
  2. 0.75–0.85: To filter out users with clear and convincing evidence of fraud.
  3. 0.90–0.95: For filtering users that are almost certainly fraudulent (beyond a reasonable doubt).
  4. 1: For blocking only the most egregious offenders (deterministic approach).

• SSP List: Select SSPs to add to the blocklist. The list shows both Active and Paused SSPs. Users can add exceptions, which vary depending on the list type:

  • Device ID (IFA) Block List: Enter device IDs (IFAs) separated by commas, either manually or from saved files. The folder for saved files is labeled "Device ID (IFA)". Note that values are case-sensitive.
  • OTT Block List: Add bundle exceptions either manually or from saved files. The folder for saved files is labeled "Domain|Bundle". Note that values are case-sensitive.
  • IPv4 Block List: Add IP exceptions either manually or from saved files. The folder for saved files is labeled "IP". Ensure that values are entered in IPv4 format only; IP address ranges are not supported. Note that values are case-sensitive.

When exceptions are applied to an SSP, a small label marked 'Exceptions' will appear next to the collapsed SSP name in the list of SSPs. This visual indicator helps users quickly identify which SSPs have exceptions configured.

• Use this list for all SSPs toggle: Apply the blocklist globally to all SSPs. Exceptions can be adjusted individually for each SSP. After the toggle is turned off, checkboxes will be unchecked, but the exception values will remain for future use.

• Save/Cancel buttons: Confirm or cancel changes.

Filtered HTTP requests will be marked with the corresponding filter reason, providing clear insights into why specific requests were blocked
