We have both options: 1. Exit Intent - track mouse position, show offer when you are about to leave
2. BounceBack - show offer when you click the Back button and only in cases if you would leave site. If you click Back again, you get sent to the previous page (for example, search engine)
Back button hijacking like this is spam. Please stop selling this product. When someone hits the back button they want to leave. Forcing them to stay on the site after that action is wrong. Shameful. I know you won't care, because people who create things like this don't have an ethical compass, but sometimes I just can't help myself.
I agree. There is one legitimate use of this type of product and that is at the end of sale funnel. I have found on one of my sites where the customer is shown the final confirmation page that they sometimes leave without submitting even though their intent is to complete. It seems that some (most) customer don’t (can’t) read and think that they don’t need to confirm their order is correct. If they click away or back out at this stage I ask them if they really want to do this as they have not yet submitted their order. I find I catch around 15% of customers at this point turn around and submit the order after getting this message so I can only assume that I have saved them from a mistake.
Another legitimate use is when you're in the middle of designing something (drawing app, for example) that you might have spent a long time on and hitting the back button will lose your progress.
You won't have a single serious customer that is going to hijack the back button.
So, if you want to do a legit business, you better stop offering this option.
While it's an "ethical" choice, it's also a question of what kind of customer you want to have.
Moreover, I think Google penalizes websites that prevent user from going back to a search result they provided (not completely sure though).
Thanks! Conversion rates for campaigns depend on the type of site, traffic quality, the targetting options you choose and ofcourse - banners and offers. But in general - they are lower for campaigns targeted to visitors that don't engage and want to leave straight away (0.1-2%), and higher when users have spent some time on the site, and really high (10+%), when campaigns are shown to visitors who started purchase process but for some reason decided to leave.
This would suggest that the only ethical use of this is for encouraging conversions of those that really do want to go ahead but are wavering because of the cost. What we need is some sort of extension that will automatically detect if a lower price is being offered if you back out :)
