I have multiple form pages and one thank you-page. I want to track if a form has successfully submitted, but I don't know how.
When a user submits a form and gets redirected to the thank you page, it'll add different parameters to the url of the thank you page. This depends on where the user came from.
E.g www.mywebsite.com/page/nameofpage?chronoform=nameofpage&event=submit
How can I track this?
You can set this up completely outside of Chronoforms. Within Google Analytics, go to Admin section, then Goals and set up a new website goal. The key is to select it to be a destination type goal and set that to your thank you page url.

If you want to have the conversion work in Google Adwords conversions as well, you will need to add a code snippet to a custom HTML module in the debug position: https://support.google.com/adwords/answer/6331314
