The difficult task of generating some meaningful and accurate numbers to justify your investments in rich content on your site has just gotten easier. Google Analytics, a popular website analysis tool amongst small to mid-sized businesses, has just been updated to now track user engagements that include elements common with Web 2.0 services, including Javascript, Ajax and Flash applications, widgets and gadgets, and downloadable pages.

This not only allows companies to better track their website numbers as a whole, it also allows them to offer advertisers alternate numbers to page views for gauging the success of an ad. New figures such as time spent on a page or the length of time an ad is visible may become more valuable to advertisers in the future.
