Register your own segments for targeting in Marketplace Packages

Marketplace Partners
Last Updated: June 23, 2026•

When creating Marketplace Packages, you can target publicly available third-party data segments, custom segments created for you by Data Vendors, or your own segments. To target your own segments, you must first register them with Index. Once registered, your segments will appear as a targeting option when you create Marketplace Packages. You can later edit them individually or in bulk as needed.

  1. Enter your email address and password to log in to the Index UI at app.indexexchange.com.

  2. If you have more than one account, select the account that you want to access.

  3. Go to Segments.
  4. Click REGISTER SEGMENT.
  5. In the Name field, enter a name for your segment.
    • It is recommended that you follow a consistent naming pattern, where you use the > character to break down segment hierarchies. Use a Type > Detail pattern. For example, Demo > Female 18-24 or Shopping > Purchase Intent > Auto.

    • Leading spaces or special characters (other than >) are not allowed.

      Note: If you're not the data distributor for the segment, get the values for Name and Segment ID as assigned in the data distribution platform.

  6. In the Segment ID field, enter the segment ID as assigned in the data distribution platform. If the data originated from a third-party distributor, use the external ID they assigned, otherwise, enter your own ID. This value can't be changed after the segment is registered.
  7. In the Data distributor drop-down list, select the data platform that's providing the data for this segment. This value can't be changed after the segment is registered.
  8. In the Attributes section, add attributes that describe and categorize the segment.

    Note: Attributes are purely informational. The values you provide are used only to improve segment discovery and have no impact on targeting eligibility.
