Does anyone know if Google Analytics has been having issues with accuracy lately? I use Google Analytics and Stat Counter on my blog, and they have generally been in line with each other. For some reason, Google Analytics has lately been off by over 10% lately. I use WordPress, so I know both analytics programs are installed site-wide.
Here’s a comparison:
January 2011 Google Analytics: 45,167 Visits
January 2011 Stat Counter: 45,227 Visits
Off by .13%
January 2012 Google Analytics: 54,627 Visits
January 2012 Stat Counter: 66,045 Visits
Off by 17.2%
I talked to a couple other people who have notice issues with Google Analytics reporting. Ordinarily, I would attribute it to Google not counting bots or something, but it’s strange since GA and SC numbers previously jived pretty well. February and March visitor numbers show a similar difference between GA and SC.
Is anyone else experiencing the same issue? What could be the problem?
