Since there are several traffic meters running here at DM on Scientopia, I was curious as to how the GoogleAnalytics, Sitemeter and WordPress in house statistics compare.
The WordPress views and the SiteMeter pageviews seem to match up quite nicely. As usual, SiteMeter visits run in good correlation with, but lower than, the Sitemeter pageviews. Surprisingly, Google Analytics visits are a bit out of register with other numbers.
Takehome message would appear to be that you can't readily compare GA numbers to the other ones, right?
