I'm using Piwigo statistic and the number of visitors in Google is different from my statistic, how can it be? for example yesterday I got alot of visitors from china, Beijing, and Google doesn't show them... what is the reason for this? this is the beginning of all the addresses (ip): 123.125.66.**
All the analytics tools give you the approximate numbers and not the exact numbers. Are you sure Google isn't showing a single visitor from Beijing? If yes, then either they were not human visitors or some other issue. Can't tell much without the details.
yes i'm sure. how can I know if they were not human? what other details do you need? what other issue?
