We can’t guarantee a low bounce rate or a high time spent on site. However, on average, we see a ~30% bounce rate and ~1 minute average time spent on site. This number will vary depending on the quality of your site and how engaging it is; you won’t see a high bounce rate or a very low “time spent on site” with traditional PPC visitors. However, pop-under ads by nature have a higher bounce rate, which is usually the result of a percentage of your visitors closing the window before browsing the rest of your site.
