We are directing traffic to a landing page that has a whitepaper. We would like for known visitors to click on the asset and have the blind form submit in the background to track, they will then access the whitepaper without filling the form (just on a click).
For unknown visitors, we will like the form to show up so that we can capture their information. Is this possible on a non-Marketo landing page?
Sounds like you just need to use Known Visitor HTML ("If Known Visitor, Show Custom HTML" in Form Editor » Settings).
(This'll work on either a Marketo or non-Marketo LP.)
