We've developed a suite of tools for taking analytics to a new, more personal level. We use our own analytics to observe which of several combinations of layouts have the best impact for each individual person visiting your site. The data is deidentified before leaving the browser, so this system works even with authenticated sites. We then use this information to suggest iterative refinements, design changes, and can even track the effects of campaign tags on each class of person. The visual changes can be applied in the browser or by the server, and any module can be used independently of the others, so this is a perfect addition to an existing site or to a suite of offerings by web designers.
