Hey, I provide a platform for an online service used by multiple websites (my partners) These partners use a registration form I host in an iframe inside their own registration page. I'd like to improve UI and A/B test the some changes to the form. The page following the registration form is also hosted by the partners and is also the same page they use for regualr log-ins. It is the same URL. i.e. If a user logs in or registers they'll reach the same page. with these issues: 1. The page I want to test being in an iframe in a domain not controlled by me 2. The "success" page being the same as regular logins 3. The "success" page not being controlled by me. Can i still A/B test my form? Thanks, D.
