The Problem
Previously, Topsort offered limited ability to create audience segments in the UI, and there was no centralized place for marketplace users to view and manage all existing audiences.The Solution
Topsort now offers a powerful new Audience Builder feature, a central place to create and manage segments. The new Audiences tab in the marketplace Admin Dashboard displays every audience with its name, source type, and user count in a single table. From the Audiences tab, marketplace users can create segments using three methods:- Upload via CSV: Upload a file of opaque user IDs directly from your computer. Once processed, the audience appears in the table with its calculated size.
- Behavioral Audiences: Build audiences by filtering users based on their past behavior, such as views, clicks, or purchases on specific products or any products within specific categories, within the last 7, 30, or 90 days. Include filters can be combined with ANY (or) or ALL (and), and exclude filters remove unwanted users.
- Combined Lists (new): Create a new audience by combining previously uploaded lists using logical rules. Add up to two include groups (each with up to 3 lists) using Any (union) or All (intersection) logic, connected by OR. An optional exclude block removes users from the final audience.
How It Works
Navigate to Audiences
Open the Audiences tab in the Admin Dashboard sidebar. You’ll see a table of all audiences available to your account with their source type and user count.
Create an Audience
Click Create Audience and choose your method: Upload via CSV, Behavioral Audience, or Combined Lists.
Configure Your Audience
Follow the guided flow for your chosen type. For CSV uploads, provide your file. For behavioral audiences, set your include/exclude filters. For combined lists, use include and exclude blocks to layer your existing uploaded lists.
