I'm trying to track how long a person who filled out a form was on my site afterwards

Basically I have a form, they enter their information, and then get sent to another page where they watch a video.  I want to track how long they were on the second page.  

Any thoughts how to do this with JotForm ?

We do have our Analytics tool https://www.jotform.com/form-analytics/, that you can check.

Also, we have Google analytics widget: https://widgets.jotform.com/widget/google_analytics that might help.

Please let us know if you have any further questions.

Thank you!
