How to check form trafic sources

Hi-I need help customizing this particular support: http://www.jotform.com/help/287-Include-Referrer-in-form-within-IFRAME for one of my forms. I want to add this referrer tag, but I want to make sure I am doing it correctly for this form: http://www.jotform.com//?formID=50275490502955.  This referrer tag will show where submissions came from? ie: organic, paid or direct traffic? 

Thank you for contacting us.

The referrer from mentioned guide is actually related to the HTTP referer. It helps to catch the web address where the form is embedded, but it does not catch anything else.

I see that you have a Google Universal Analytics widget on form. Does it work properly?

We are very excited to announce that today we launched Form Analytics, a new feature that will let you know more about the traffic of your form, as well as platforms used, conversion rates, devices and locations:
