How to use visit duration for triggering goals


#1

I’m (ab)using custom variables and the client-side clock to fire Piwik goals like »Visit has been at least 5 minutes long«. Here’s how:

In the regular Piwik code at the bottom of your html page, just add following code, right before piwikTracker.trackPageView();


var currentTime = new Date();
var mystamp = currentTime.getTime();
var piwikStart;
if (piwikStart = piwikTracker.getCustomVariable(1)) {
  if ((mystamp - piwikStart[1]) > 300000 ) { piwikTracker.trackGoal(99); }
} else {
  piwikTracker.setCustomVariable( 1, "StartTime", ""+mystamp, "visit");
}


  • Where 300000 is the amount of milliseconds for this goal, in this case 5 minutes = 300 seconds = 300000 milliseconds
  • Where 99 is the id of your goal, which you have to configure before adding this code. It has to fire »manually«, of course. That’s what we do here.
