Hi, for starters, there's an "f" missing in your link.

Visit my article on http://captainmnemo.net/en/general/90-how-to-develop-a-successful-internet-strategy.html which I will update in a few days regarding metrics. See my comment at http://www.seodesignsolutions.com/blog/seo-marketing/seo-visibility-and-conversion/comment-page-1/#comment-36846 where I try to question a few metrics ideas. Get Firefox browser and install addons "Quirk" and "SEObar", the give you lots of that information. Check out http://www.seoptimise.com/blog/2008/08/33-website-success-metrics-instead-of-rankings-google-pagerank-and-traffic.html and, obviously, just google the term "website metrics". They've probably already written your thesis for you ;-)

Kind regards
