We have a resource page set up with a munchkin code that contains links to PDFs. I set up a trigger campaign that is set up as follows:
Clicks link on Web Page
Link name: contains = (name of PDF, in the URL name when you hover the mouse over)
Web Page: is: (the webpage with a munchkin code - no query string)
Querystring: contains = (city name)
I know that you can't track PDFs, but can you track clicks that open PDFs?
