What does the past visits rule do?
The past visits rule shows the lightbox to visitors based on how many times they have visited your site.
Use this rule to show a special offer to repeat visitors to a particular product page in order to encourage them to make a purchase. This rule is different from “Page Visits” in that this is the number of times they have visited your site. For example if I go to your website, then come back 2 days later, the number of past visits is 1.
