Open up a Preview and perform the specified promise/action you've set up in your Goal and see that you get the Goal satisfied popup in the upper left corner.
If you don't get this popup, please check that you've set up the Goal correctly. Otherwise, the Goal won't register any conversions. Learn how to Create a goal.
NOTICE:
- Goals are triggered only after the Audience has been TRUE for the visitor.
- The Goal does not need to be set on the page where you do your changes. In other words, the goal can be triggered on a page where Audience is FALSE, but only if the visitor has fulfilled the Audience statements before that.
- Remember to check that your goals work correctly in all variations
