A goal is a predefined target of what you wish to keep track of, f.e. Subscribing to the newsletter.
You can define and track goals and sales by going to the Campaigns tab -> Select the campaign you want to modify -> Go to the category ‘Goals’.
Under ‘Goals and Sales’ you are able to set goals with corresponding criteria.
Adding a goal requires you to name the goal, add criteria, and a value. Setting criteria allows you to define a certain customer pattern on the website e.g. a customer entering the thank you-page after subscribing to the newsletter can be installed to define a goal.
