The query parameters you collect can be given user-friendly names and organized into categories that best meet your organization’s needs. Instead of searching for the query parameter, WT.mc_id, for example, you can name it “Marketing Campaign ID” and add it to your “Campaigns” category. Doing so enables users to more easily access data in familiar terms.
The parameter names you configure in Account Settings are then made available in the Explore menu when selecting a dimension or when creating segments or measures.
To learn more about how to add your custom parameters and how to customize the Explore menu, see Managing Parameter Names in the Explore Menu.
