You can use new ways to visualize analytical data about your website. Understanding how your site visitors interact with the site can help you deliver a better experience, such as setting up a site promotion. Being able to view the data about your website in the context of the site makes the information more accessible.
Statistical data about your site is represented graphically and displayed over the resource as a graphic. You can see a usage curve for a specific portlet over a specified time period. You can see which resources, such as pages or portlets, are being viewed the most by your site users.
The overlay graphic is dependent upon a integration with a web analytic solution, such as Coremetrics, Omniture, or Webtrends. The analytic aggregator captures site data, analyzes it, and sends the analyzed data back to your site where it can be displayed as a graphical overlay.
When you set up a site promotion, you can assign custom tags to the content. A site promotion is the web content portion of a marketing campaign. The assigned tags help you determine how successful the site promotion is.
