I wonder if the time delay on these pop-ups is set to avoid being measured by the &quot;bounce rate&quot; or &quot;0-10 second session duration&quot; analytics tools.<p>This would be especially interesting to measure. While the 0-10 second bounce rate on any site will be somewhat high due to people just looking for something other than the page you give them (I see 50% bounces on a small business site with zero ads), and it&#x27;s difficult to distinguish these from people who didn&#x27;t like the ads or format, you could get a precise measurement of exactly how many people close the page within 3 seconds of the pop-up appearing.
