I found the answer ----- help to others
you mentioned about heatmap.
A quick question:
- which URL should I put in hotjar : New Heatmap --> Name (see in screenshot)
my domain OR campaign URL created by tracker using my domain as LP.
----as long as the Page which has the heatmap code is integrated or part of the URL , should be FINE
- if only has tracking URL provided by CPA Offer, does that mean there is NO way to track heatmap ?
---- NO, you have to see question 1 answer.
