Google Analytics Review
Google Analytics (GA) is a free service that does a great job at high level analytics such as traffic sources, visitor counts and statistics on your content. However the event-based tracking is not as sophisticated as Mixpanel or Kissmetrics, so GA is usually used in conjunction with one of those services as well.
