Is there a way to track were a lead is from?

We have some leads that come to our form via just our home page at sleefs.com but some are coming directly from Ads we have running on Facebook. Is there a way to add some code so that in each lead we can attached were they came to the form from?

One solution would be using the Get Referrer widget, as it would allow you to find out from where did the form submitters land into the form: https://widgets.jotform.com/widget/get_referrer

I hope this helps. If you need further assistance please let us know. Thank you.
