Another theory i am now investigating is that maybe the exponential increase in mobile device usage has something to do with with this dead beat zombie traffic. Mobile devices convert badly, it is a known fact. Maybe the reason i am seeing more sales over the weekend and late at night is because more people have the time to seat in front of their good old pcs at home on weekends?... will definitely look into this further in upcoming weeks.

I think you could be right about this... great theory. I certainly see lots of referrals not converting during working hours and then in the evening the enquiries pick-up.

Having come onto the site from my iPhone I can see a large majority of daytime visitors seem to be from mobile devices (same style of referring URL).

Very well spotted, I think you are onto something.
