I'm not 100% clear on what "original source info" means.
Since it always seemed to have a URL, I thought it was the landing page, or the first page they hit that had munchkin code. But then I see that sometimes original source info is a form, not a URL.
So not 100% clear on what it means.
If someone fills out a form on a Marketo landing page that has Marketo form on it, will the original source type be the URL, or the form?
