Do people buy more when products are presented horizontally across the page or when they are presented vertically on the left?
My company is in the first stages of redesigning one of our e-commerce websites. Currently on non-mobile devices, our products (non-physical, if it makes a difference) are presented on the right side of the page under the header:
We are moving towards either:
1) Showing the products in their current stacked layout, but on the left side of the page:
Or 2) Showing the products in a side-by-side pricing table that stretches horizontally:
Has there been any UX case studies done as to customer behavior differences between the two new options? If it's specific to conversion rates and display on non-phone devices, that would be great. (I read through a StackExchange question about "order of prices and effects on sales", but it didn't address the change in layout/positioning.)
