Some users of Google Website Optimizer have been experiencing some problems with the service. It appears Google has heard the complaints, and fixed the issues accordingly.
In a post to Google’s Website Optimizer blog, Google Analytics Sr. Product Manager Enrique Muñoz Torres writes:
We have gotten reports of spurious conversions appearing in Website Optimizer reports over the last few days. We have since fixed the underlying problem and reprocessed the affected data. Please do let us know if you still see any problems with the numbers in your reports. We apologize for the inconvenience.
Of course Website Optimizer will soon be going away. A week ago, Google announced the launch of Content Experiments in Google Analytics. This will let webmasters test different versions of pages right from Google Analytics itself, eliminating the need for a standalone product in Website Optimizer.
Google says Website Optimzer will be going away on August 1.
