Probably people click Back in browser or go to other website via ads and from here to Google again.
Wonder if you can improve the site-performance measure by setting all links to open in a new window, so there is no back button to hit. Your page still stays open and the user is still on your site, as they close those windows. Right? All my links are set to open on top, rather than in a new window, because years ago, when I programmed the site, there were popup-blocker issues in some browsers for opening new windows (I am not sure if these are still an issue today). Does it create a negative user experience to open a new window, and does it keep the user on the site longer (thereby improving the site's user/performance score)?
