Hey Rick 👋

I had to do a bit of digging for this so apologies for a delay here.

If you mean modifying the expiration date of Unbounce cookies, Unbounce cookies cannot be modified due to privacy policy concerns.

You could potentially overwrite our cookie with custom code, but I wouldn’t advise it: https://stackoverflow.com/questions/4863740/change-cookie-expiry-date-http

If you’re worried about the cookie lasting too long, Google Analytics and Floodlight could be a good option for you: https://support.google.com/searchads/answer/7298761?hl=en

Hope that helps for now! Let me know if you have any questions 🙂
