Given pervasive confusion around analytics terminology, I lauded the Web Analytics Association's August, 2007 announcement of Report Definition Standards, but was somewhat skeptical with regard to how vendors might use the cloak of compliance to make it harder for you to interpret their report definitions.

Fast forward to March 9, 2008, and IndexTools' COO Dennis Mortensen posted a refreshingly comprehensive, easy to understand, and transparent list of how the IndexTool's solution complies (or doesn't) with the standards.

Critically, Mortensen describes the methodology IndexTools uses to make the calculations, which lies at the crux of using the standards definitions to understand reports generated from any product.

Mortensen's post must also rank as an industry first for a vendor to actually go public that their product cannot produce every metric under the sun, making it far easier for you to potentially draw an "apples to apples" comparison and clearly see what you get, and what you don't, from a basic reporting perspective.

All of the other web analytics vendors...especially those with the largest customer bases, such as Omniture, Google Analytics, Nedstat, ClickTracks, Unica, Coremetrics' and WebTrends should step up and clarify in similar terms how they meet (or not) these standards.
