For developers that would like to track the usage of your Windows Phone app that are in the marketplace. Google Analytics is actually a decent choice given that setting up is fairly easy.
Simply head over to http://www.google.com/analytics/ and login with your existing Google Account. Next click on the “Admin” tab for administration controls to create a new account as shown in the screenshot below.
In the next page, you will be presented with the Tracking ID.
Now we will move on to how to use the Tracking ID. The Google Analytics SDK is available on codeplex. Alternatively you could get it through Nuget by searching for “Google Analytics SDK for Windows 8 and Windows Phone”.
After the SDk is installed, you will see an analytics.xml file appearing in your project. For Google Analytics to work, we would just need to uncomment one entry in the xml file. Uncomment the below code and add in your Tracking ID.
For another advance features of the SDK, please refer to the documentation at codeplex
Some examples of the other features are such as page tracking, event tracking and exceptions.
