Google’s web statistics service Google Analytics was partly showing the wrong value for “Absolute Unique Visitors,”. This bug is fixed now, Google says, and was only restricted to the Absolute Unique Visitors details report page, and not the value as taken from the Visitors overview page.
The Google Analytics blog say —”The number of Absolute Unique Visitors displayed in the Visitors Overview report previously did not match the number of unique visitors in the Absolute Unique Visitors report. This is because the Absolute Unique Visitor report shows data over time and was therefore summing daily unique visitors. The Absolute Unique Visitors report no longer sums the day by day totals but instead displays the absolute unique visitors metric that is displayed in the Visitors Overview.
Careful, this one's a bit geeky. We recently changed the way we ordered URL parameters. Why is this important? Take a look at the following two URLs:
Instead of considering these two URLs as a single URL: www.google.com?beds=2&rooms=3 (i.e. alphabetically ordered parameters), we now consider these as two separate URLs (i.e. without reordered parameters). We made this change to accommodate those of you with filters or goals dependent upon parameter order.
