Have an option in your pop up management software to request a test where the pop-up will be displayed at random intervals. The more conversions you have for some of the times and the less for other the system will start showing the better ones more and drop the worst performing ones.
Each web page will have different elements that work for it. The “buy” button that converts best on one page can be very different than the one that works on another website.
