 Dimensions are attributes of your dataset. Using them in queries enables analyzing and compare multiple groups against each other.
 Think of them as `GROUP BY` in SQL.

 Valid dimensions include:
 
 | Dimension | Example | Description |
 | --- | --- | --- |
 | `event:goal` | Register | A custom action that you want your users to take. To use this dimension, you first need to configure some goals in the site settings, or via the Sites API. Learn more about goals here. |
