I am wondering if (known) visitor's time on page can be tracked/measured. Like, visitor is on page for at least 30 seconds.
Intention behind this is to use this for behavior scoring. Like, if the visitor spends at least 30 seconds on any page (either company web site or Marketo landing page) increment his/her behavior score by 1.
Is there any way to do this? If yes, I would deeply appreciate any help with this.
