Remarkably, of those direct marketers, marketing services providers and agencies queried, 70% said they perform little or no results analysis to determine the effectiveness of their online campaigns, despite the availability of accurate testing and measuring tools.
One Analytic Does Not Fit All
Optimized online marketing effectiveness is accomplished by testing, measuring and analyzing data from a variety of metrics, then redeploying the campaign reflecting lessons learned from the assessment. Analysis generally falls into one of two categories, quantitative or qualitative.
Quantitative optimization involves testing different design versions and allowing your customers' response to identify the more favorable layout. These tests are often referred to as A/B or multivariate testing. Proper assessment and subsequent application of quantitative data can substantially enhance campaign conversion rates.
Live usability testing and focus groups are examples of qualitative research techniques that can be used to validate quantitative findings or expose information quantitative analysis is incapable of providing. Qualitative research can help ferret out usability issues, behavioral tendencies or navigational inconsistencies that can quickly distract or lose today's impatient online visitors.
Or Just Ask
Understanding where and why conversion rates drop off only provides part of the story. Often the customer will alert you to obstacles to success you haven't even considered, if you just ask. Online surveys can complete the picture and reveal additions or modifications impossible to gather from behavioral data alone.
Too Much Data, Lacking Expertise or Time
Honing the design, messaging, timing and other aspects of your email campaign based on proper assessments of empirical data is crucial to optimizing online marketing results. However, analytical tools are often inaccessible, arcane or overwhelmingly voluminous.
Consider working with a competent firm that can help assess your marketing efforts and optimize the return on your online investment with appropriate brand considerations, design aesthetics and testing capabilities."
Mandriva Linux 2007 for Home Users

What might a Linux distribution such as Mandriva Linux 2007 be to a Windows user?
Is it a valuable alternative, or do you have to be a real computer nerd to risk the move? Why would an average PC user make the effort to change over to Linux? Admittedly, not necessarily everyone will benefit from such a move — but it could be a lot more interesting than you may suspect. Many discussions around this topic lead to considerable debate, and in this article we do not pretend to own the truth or to be complete. This article just sums up our own experiences after several years of use of both Microsoft Windows and Mandriva Linux.
We wrote with our Mandriva experiences in mind; however most modern Linux distributions offer similar benefits.

String theory is arguably the most popular theory in theoretical physics; that is, it cannot be proven. The idea, is everything you see around you is made up of tiny strands of energy that vibrate at different frequencies. Until now, experimental verification has not been possible; but researchers at the University of California, Carnegie Mellon University, and The University of Texas are planning a definitive test with the future launch of the Large Hadron Collider in Switzerland that could disprove the current theory.
Similar to the well known U.S. particle collider at Fermi Lab, the Large Hadron Collider, scheduled for November 2007, is expected to be the largest, and highest energy particle accelerator in existence; it will use liquid helium cooled superconducting magnets to produce electric fields that will propel particles to near light speeds in a 16.7 mile circular tunnel. They then introduce a new particle into the accelerator, which collides with the existing ones, scattering many other mysterious subatomic particles about.
It is with this accelerator, that will allow researchers to begin observing the scattering of W bosons, an elementary particle that is one of the four fundamental interactions of nature and required in the proposed testing of the current string theory. I use "current" because string theory is just that, a theory; and it is constantly changing as more information becomes available.
"Our work shows that, in principle, string theory can be tested in a non-trivial way," said Ira Rothstein, co-author of the paper and professor of physics at Carnegie Mellon.
"The beauty of our test is the simplicity of its assumptions," said Benjamin Grinstein, a professor of physics at the University of California "The canonical forms of string theory include three mathematical assumptions — Lorentz invariance, analyticity and unitarity. Our test sets bounds on these assumptions."
Grinstein also noted that if their test does not substantiate what the theory predicts, one of the key mathematical assumptions about the current string theory would be incorrect."
