How to find web page URL where my form is embedded?

I recently discovered a form we created years back that is getting newsletter subscribers, but I'm not sure how people are finding the form.  I don't have a way to search my site for the url to the form. 

Is there any way to use a hidden field or a widget to track traffic leading to the form?  Maybe with Google Analytics widget? 

Thanks for any assistance you can provide.

You can easily capture web page URL where your form is embedded using our Get Page URL widget.
