As you may know, we began offering Optimized Design for websites several months ago. This service helps companies develop or redesign sites in a manner that is both effective from a user perspective and also properly optimized for Natural Search.
Internet Retailer recently held a Web Design conference for advertisers, focused not only on the aesthetics of web design but also on Website Usability. They did a pre-conference survey and asked the top 500 retailers if they're doing multivariate or A/B testing, and amazingly, 76.7% of retailers surveyed don't conduct these types of tests!
