In the latest Chrome browser versions a page may be fully loaded and rendered (incl. SiteCatalyst code) before the user actually requests the page, which can lead to distorted engagement metrics. For example, if you search for "omniture.com" on Google, you can see in Chrome's task manager that the Omniture homepage is being prerendered in the background (screenshot attached). It would be great if Omniture would provide a JavaScript plug-in that makes use of Google's Page Visibility API (http://code.google.com/intl/fi/chrome/whitepapers/pagevisibility.html) to deal with this issue.
