Google Analytics is a freemium web analytics service offered by Google that tracks and reports website traffic. Google launched the service in November 2005 after acquiring Urchin. It is now the most widely used web analytics service on the Internet. Google Analytics is offered also in two additional versions: the subscription based Analytics 360, previously Google Analytics Premium, targeted at enterprise users and Google Analytics for Mobile Apps, an SDK that allows gathering usage data from iOS and Android Apps.
Its approach is to show high-level, dashboard-type data for the casual user, and more in-depth data further into the report set. Analytics analysis can identify poorly performing pages with techniques such as funnel visualization, where visitors came from (referrers), how long they stayed and their geographical position. It also provides more advanced features, including custom visitor segmentation.
