Google has released a fix for Google Analytics that corrects a traffic reporting bug introduced by an update to the service last week.
On August 11, Google changed the way Analytics calculates user sessions on websites. But the change also added a bug that misrepresented traffic in some situations.
Since the update arrived, UK-based webmaster Neil Mordecai noticed that his site was vastly under-reporting the number of new users and over-reporting the number of returning users. "Google Analytics have released a buggy version of their system. Since last week...they've been counting on two hands," he told The Register on Wednesday.
"Before the 11th August 'first visit' traffic was typically 80% of the total traffic with 'same day returns' being less 10% - this pattern extends long into the past. After 11 August, 'first visit' traffic dropped well below 50% and 'same day returns' rose to well over 50%."
