Overview
Interests is an audience sourcing option available in Prospecting campaigns. Use it to discover and apply third-party interest segments, reaching households based on browsing behaviors, demographics, and purchase histories sourced from multiple data providers.
Interest targeting supports a more intuitive discovery experience, allowing you to describe your audience, explore relevant segments, and refine your selection without needing exact segment names. Selected segments are reflected in your audience composition in real time.

Build Your Audience
Discover segments
Discover interest segments by describing your audience. When you open Interests while creating a new audience, you’ll start with a guided discovery page.
From here, you can:
Search using descriptive terms (for example: “travel insurance” or “high income”)
Use suggested audience categories to quickly apply filters
Filters can be applied from suggested categories, search inputs, and advanced filters (such as provider or vertical)
All filters work together and update results in real time.
📝 Note: The discovery page appears when creating a new audience. When editing an existing audience, you will see the segment selection view directly instead.
For MNTN Select Customers
If you run MNTN Select campaigns, you may have access to Select Reached Audiences in Interests. Select Reached Audiences let you build audiences using households that previously saw your Select campaign.
Use Select Reached Audiences to:
Re-engage households who previously saw your Select campaign
Sequence messaging across campaigns
Extend awareness campaigns with a follow-up strategy
Include or exclude Select-reached households in audience logic
To locate Select Reached Audiences, on the Interests tab, search for Select.
Available segments follow this naming format:
MNTN Select: Households Reached in [Bundle Name]
📝 Note: Select Reached Audiences are tied to prior Select campaign exposure. Segments begin appearing after your Select campaign starts serving impressions and households have been reached.
Evaluate segments
Review segment details before selecting:

You’ll also see additional details directly in the results table, including data provider and audience size. This helps you understand what each segment represents before adding it to your audience.

Select Excl to exclude a segment

📝 Note: If no number is associated with an interest segment, then no households are associated with this segment. The data provider has likely deprecated the segment. Please avoid using these segments when building out your third-party audience.
