Hi, i'm using
Traffic Source ->
So the Voluum campaign URL is used both by the traffic source and the Lander CTA?
Correct flow, wrong on the links.
The campaign link you use in your ads, it interprets the traffic and redirects to your lander. Now, on your lander, your CTA should be http://something.trackvoluum.com/click
You find the correct link in the settings section. The 'something' will just be your custom account code, e.g. szgeb or bhyui, etc., or your CNAMEd domain.
