Sometimes less is better for increasing the conversion rates of a website. At Findlaw, we redesigned the Lawyers.FindLaw.com website to a more modern and more mobile-friendly website. In our user tests (we sent half the users to the newly redesign and the other half to the old website), we found the new website were generating better conversions.
I was one of the Front End developers who worked on the redesign of the Lawyers.Findlaw.com website. In this project, the website was based on JSP and XSL templates and we used the Zurb Foundation as the base of the CSS classes.
