What do you recommend for "cookie duration?"

What do you recommend for “cookie duration?”
Cookie duration determines how much time must pass before any visitor will see your same pop up again, and we generally recommend no less than 60 minutes.
Anything less and you might annoy some visitors.
Many believe the “best practice” on this is 24 hours, in which case you’d enter 1440 minutes.
This means visitors will only see your pops once a day.
While you can technically set the cookie duration to 0, we REALLY don’t recommend that as it WILL irritate your visitors.
For example, if the visitor moves their mouse around the edges of their browser window for some reason, your exit pop up will keep appearing and re-appearing.
