These classifications power filters, breakdowns, and metrics throughout your dashboards. ## Key Segmentation Dimensions Groups orders by sales channel, integration path, acquisition source, and special order types Subscription vs one-time classification using multi-signal detection ## How Segmentation Works Each segmentation dimension uses a **determination hierarchy** that evaluates multiple signals to assign the correct classification. The system prioritizes explicit signals (like platform integrations and exclusion tags) over inferred signals (like order tags and UTMs). For example, a TikTok Shop order from a direct integration is always classified as `TikTok Shop`—even if your config sheet has a rule that would otherwise match it. See each dimension's page for the specific hierarchy and signal priority used. ## Customizing Segmentation You can override default channel assignments using the **Channel Mapping** tab in your configuration sheet. This allows you to: * Map specific UTM patterns to custom channels * Group orders by discount codes * Segment by order tags or SKUs * Assign orders to vendors for cost tracking Step-by-step guide to setting up custom channel mapping rules ## Related Resources Full list of available dimensions including sm\_channel and sm\_sub\_channel How UTM attribution data is selected when multiple sources exist
