Hi Alexia
Also since you have two criteria:
1 Clicks a link on a Website
2 Visits a Landgin Page
The trigger in the Campaign would need to be on the second action i.e. Visits Landing Page
You will also need a filter for the first action.
This is becuase you only want to trigger after they have completed the second action but also ensure that you filter for the leads / records that have also completed the previous action.
