<a href="file.pdf" onClick="adwords_conversion();return true">Download PDF</a>where adwords_conversion() could be a JavaScript function (located in the page head section) containing the adwords conversion code.
Is such an onClick action a reliable method for tracking clicks on PDF (or any other) files on a web page? Any experiences?
It would be very helpful to avoid dynamic redirect pages for tracking because search-engine indexing (and PageRank transfer and so on) of the PDF document would not be affected ...
Key question: Is the onClick request always executed? What if the PDF request is faster?
