Thank you guys! I sent an email to Gabriel who is the creator or the plugin. These are his thoughts.
Hi Shilpan,
It is unknown how Google Analytics counts visits. The difference can be caused for example by:
- Google Analytics uses JavaScript to load itself. So it just counts visits if and only if the browser loaded the GA Javascript file AND executed it successfully (JS supported, no connection timed out…). Being server-side, Counterize doesn’t require JavaScript to count visits, except for outlinks statistics.
- Google Analytics probably discard visits of browsers it doesn’t support, plus they probably have a huge bot exclude list. Counterize only excludes the visits that match the botlist.txt file and/or the visits having their IP filtered.
There are probably many other reasons, the way Google Analytics track visits is like a black box. I believe that Counterize stats are more accurate than Google’s.
Hope this helps !
