Our 'Absolute Unique Visitors' in GA seems to be far too high. For example, it says that in the last week, we've been visited by 127633 'people'. To put this in context, we have around 16000 students, and a few thousand staff.
From what I've read, AUV is essentially a count of the persistent cookie GA puts on the visitors computer. Is there anything that we are doing that would delete that each day or session to inflate this figure? I presume our lab computers would wipe the cookie so each new session in a lab is a new visitor. I presume most staff shut their pc's down each day, so could that do it?
The other thing that confuses me is that we have this large number of uniques, but only 26% are new visitors. I would have thought that wiping cookies - which would inflate the uniques - would skew the returning/new mix towards new visitors more than this.
