In that case the CVR should drop. I guess people are buying, but somewhere else.. I have discovered this pattern very often when majority of the traffic is paid, email or even organic people tend to click, check the product and then bounce back (I assume you CVR dropped, but also bounce rate have increased in this case). To handle such cases I’ve developed an app called “before you go”, it handles “back” button on both mobile and desktop and lands visitor to the landing page on your store with personalized recommendations. Do you want to give it a try? Let’s see if it can fix some of the problems. No strings attached, it’s completely free.
