"Earlier this week, Google announced they have changed how they define sessions in Google Analytics.That change should have only impacted about 1% or less of the traffic reports.  But webmasters and marketers were noticing major changes and felt something was wrong.  Guess what, there was something wrong.Last night, Google updated their blog post explaining the issue and said it is being fixed now.  Google said:We identified an issue responsible for unexpected traffic changes following our recent update to how sessions are defined in Google Analytics. A fix was released at 2pm PST Tuesday August 16th.The issue affected some sites using the following configurations:1. If a user comes to a customer\u2019s site with a space in some part of their traffic source data, then revisit the same landing page during that session by refreshing the page or later pressing the back button, a new session will be created for every hit to that page. (Clicking a link elsewhere on the site that leads back to the page should not matter.)2. Google Analytics implementations using multiple trackers (an unsupported configuration) are also affected when a space is included in the traffic source data. These sites will see fewer visits from new visitors, and more visits from returning visitors (with some variation due to different implementations).Again, a fix for this issue was released yesterday. Please let us know if you continue to see unexpected traffic changes. We apologize for the inconvenience and thank you for your patience and continued support.Good to see Google was able to resolve this pretty quickly.Forum discussion at WebmasterWorld."^^<http://www.w3.org/2001/XMLSchema#string>
