Can I see how many page views a form has?

I'd like the data so we can compare number of views before and after certain advertisements. 

Hi,

That's possible using the available widgets under analytics category like Google Analytics and Yandex. This enables you to track and analyze form submissions and form views. You can also add stats counter to your form if you want to. You can find more analytics widgets here: https://www.jotform.com/widgets/category/analytics

Feel free to let us know should you have further questions.

Regards!
