Until now, the de rigueur of ecommerce web design says that add-to-cart buttons belong on the right column of the screen. Crutchfield.com is breaking that convention, though, by placing the add-to-cart button on the left column. Rather than showing a screen here, you can see one on Grokdotcom’s blog post or at Crutchfield.com.
Having worked at Crutchfield for a short time a few years ago, I know that there are some brilliant minds there, and that they used to test a lot of different screen designs. I wonder if this is a test or if they have seen some data that indicates that a left-side add-to-cart button works.
In any case, I can’t believe that an add to cart button on the right side is actually more effective.
