I need to display a different link for anonymous users and register users for same content
In build &gt; elements you will need to create 2 html markup or Advanced HTML/Text elements 

Each one will have the links mentioned 


There is a setting access that you can choose who has access to it

For the other link you can choose anonymous 


For one of the elements you will choose authenticated


If this solution is not satisfactory 100% you will need to override webform
