Adding Custom Dimensions via VWO Editor
The pre-JS code snippet for custom dimension triggers on both campaign and goal pages, while the post-JS code triggers on campaign pages only.
NOTE: The pre/post JS executes only when the campaign is running. This method is best for capturing test-specific data for a running campaign.
