#### 2. Create a Custom Relationship

Follow these steps to define a custom relationship:

1. **Enter a Name**\
   Give your custom relationship a clear, descriptive name\
   &#xNAN;_(e.g., “Campaign Mapping”)_.
2. **Add a Description**\
   This step is important: the description helps Boolee understand how to apply the mapping in future analyses.\
   &#xNAN;_(e.g., “Mapping offline conversions from CSV to Google Ads campaigns”)_
3. **Define Field Mappings**\
   Set up the specific relationships between data points across platforms. Examples:
   * Map **offline conversions** from a CSV file to **Google Ads conversions**
   * Align the **Country** field across platforms like **Facebook Ads**, **Google Ads**, and **TikTok Ads**
