Last Updated: August 11, 2026

You can target segments in a Marketplace Package to reach audiences based on criteria such as demographics, interests, and purchase intent. These can be segments that Data Vendors have granted you permission to use, or your own segments that have been registered with Index.

To find the right segments to target, you don't need to know the exact segment name or ID. You can start with a broad campaignClosed A collection of multiple ads in different formats. idea, then use filters to narrow down the most relevant segments. Find these search and filter options on the segment targeting page, which appears after you click + ADD TARGETING under Segments when creating a Marketplace Package.

Recommended workflow

The most effective approach to finding relevant segments starts broad and progressively narrows down:

  1. Search: lf you don't know the segment name or ID, describe your target audience in plain language.

  2. Filter: Narrow results by attributes such as geography, channel type, or category.

Search

In the search bar, enter a full or partial segment name or ID if you know it. If you don't, describe what you're looking for in plain language, for example, frequent luxury travelers or sports fan mobile, to start broad and see what's available.

Results are drawn from segment names, IDs, and data provider names, and ranked by relevance. Segments that match all your search terms rank as exact matches and appear above segments that match only some. For example, a search for luxury travelers surfaces segments containing either or both terms, with exact matches (both terms) ranked higher than partial matches (only one term).

Exact matches (both terms):

  • Vendor 1 > Affinity > Travel > Luxury Travelers

  • Vendor 2 > Wealth > Luxury Travelers

Partial matches (one term):

  • Vendor 4 > Travel > Luxury Boutique Hotel Researchers

  • Vendor 5 > Contextual Scene Targeting > Travel > Luxury Travel & Experiences

  • Vendor 6 > US > Travel > Luxury Travel

Follow these tips for better search terms:

  • Use descriptive terms. Enter 2-4 words that are likely to appear in a segment name, rather than your internal campaign terminology.

  • Be specific. The more specific your terms, the better your results. For example, when targeting car buyers, SUV inmarket is more precise than car buyers or auto shoppers. Each word is matched independently, so word order doesn't matter.

  • Use at least two characters for each search term. Two characters is the minimum supported length, so terms like NA or 18 can return results, but one-character terms won't.

  • Pair numbers with additional terms for age-related segments. A number by itself also matches segment IDs, which can surface unrelated results. Add terms like age or demographic, for example, age 18-24 or demographic 25-34, to narrow the results. You can also use the Categories filter to refine results.

  • Try different terms if results are unexpected. Search matches on words, not meaning, so cars won't automatically surface segments named auto or automotive unless those words appear in the segment name or ID.
