You need to provide a link to your page.
Its origin as a JSP page has no bearing on tracking.
If you have tested that page with a lead that is yourself, you can look at the activity log of that lead and check that 1/ the clicks are detected and 2/ in the click activity details, see what are the parameters that you could reuse as constraints in the trigger.
Thanks for your feedback!
Unfortunately we are not able to see activities related to our issue (i.e. LP asset downloaded/click link on LP).
In fact, in the activity log we can only see other actions (like web page visited or form filled out), but for what concern all the links specified in the page, all the tracking that we use are not visible by Marketo (in the results tab of trigger).
We do not understand why this occurs, and for this reason we had thought that the issue could be releated to the transaltion from .jsp to .html.
If you have other suggestions let us know!
However, thanks a lot for your feedback. We keep it in mind for next time!
Pls send the URL of your LP.
