Do you know what your goals are? Have you let Google know? You should.
Google Analytics allows you to establish goals for your website and will even measure your goals for you so you can determine how successful you are. If you need actionable data, you can get it by measuring your goals and using the information to make necessary changes regarding how you track and measure data and how you act on the data you track and measure.
Your sales funnel is an integral part of that process. By knowing how your traffic flow should result in a sale, you can place the proper metrics where they need to be in order to tell you where in the process you are not meeting your goals. Then you can take that information and make the necessary tweaks and changes to improve the sales process. But it all begins with tracking. Google Analytics is a great tool.
