I saw a couple of posts about this topic in here but no one answered it exactly.
How are the unique visitors per period are counted?
per day - the real uniqe visitors a day
per week - it’s not the sum of all daily uniques, it’s not the average
We have piwik running in a LAN with a limited number of static IP-Adresses.
Daily uniques are ok. But the week/month/year count is far bigger, than possible.
Does it count the returning unique visitors? But how exactly?
If i query the database and convert the “location_ip” and make a “group by” the number is e.g. 1000 but the yearly uniques are 15000. But as I mentioned it is not just the sum of daily uniques, because that would be 30000. So how is that calculation performed?
PS: We’re using piwik 1.0 until they fixed the visitors bug in 1.1x.
