I found an interesting presentation by Deepak Nadig, a distinguished architect for eBay on modern day e-metrics.
He spoke recently at a Marketing Optimization Summit in San Jose (May 4 – 7, 2009) and highlighted how web 1.0 type page metrics are limiting given today’s page interactions that occur without changing a page. If you follow his bio on the conference site – you don’t get much more information. However, if you look up Deepak’s blog and then event post, you will find a copy of his 45 slide presentation. 🙂
Look for the very cool review of Yahoo site through the ages as well as heat maps tracing where the eyes go on a page.
