If you have a goal/KPI that you know you always want to measure in all your projects you can set the goal as a Standard goal. This will make this goal automatically be added to all projects that are created from now on.
Notice that you will have to save the goal as a template first and then set the template to be a standard goal.
If you have saved your goal as a template you can follow the steps below.
To do this go to My websites -> click the website -> choose Goal templates.
This will bring up a list of your goal templates. You can now click the cog icon to get the option to set a goal template as a standard goal. This will be marked with a star to the left of the goal name. The goal will now automatically be added to all projects that are created from now on.
