Google Analytics has announced that they will be deprecating compatibility with Microsoft Internet Explorer 8 (IE8) at the end of 2013. IE8 hinders the speed of innovations within the analytics service. Google Analytics will still continue to measure traffic from IE8 browsers to yourself though.
If you are an IE8 and Google Analytics users, it is recommended to upgrade to IE9 or higher. Google Analytics is also supported on the latest versions of Chrome, Firefox, and Safari.
“It is our hope that giving you more than 3 months to prepare for this change will minimize disruption to Google Analytics usage for you and your business. We will send further reminders prior to the deprecation at the end of the year, but we strongly advise you begin preparing and implementing plans,” stated the Google Analytics team in a blog post.
