You may need to build your own criterion in this case. Henrik Fransas has a blog on how you can build your own criterion in 7.5 - http://world.episerver.com/blogs/Henrik-Fransas/Dates/2015/2/building-custom-criteria-for-visitor-groups-in-episerver-7.5/
Is their a visitor group I can use for last visited page ?
I want to personalise content on the page the user is currently on from where they came from within the website.
Visited Page visitor group does not fulfil this as always remembers that i once visited this page.
