  11. Web Analytics: User Interaction • Analytics can be introduced at any stage of the web development process • With compiled RIA formats, analytics must be introduced before design is created. • Add Event handlers that then call page tags

  12. Web Analytics: Media Drop-Off • Use invisible media markers every 5 seconds inserted in media when it is initially loaded. • Media markers trigger JavaScript events • JavaScript events call page tags

  13. Web Analytics: A/B Testing • Design in XAML is separated from the code in JavaScript • Very easy to try different XAML in controlled tests • Upcoming webinar on Silverlight + Web Analytics • Tuesday, Oct 16 2007, 11:00 AM PST • Detail on my blog: http://blogs.msdn.com/synergist
