Joshua Porter makes a good point about Amazon’s product pages:

The reality is that Amazon has designed themselves into a Local Maximum. They’ve tested and tweaked the same product page over and over and they’ve optimized it as much as possible. They can’t improve it significantly at this point without making a big change. But they can’t make a big change because the only changes they can make must increase revenue (or some closely related KPI). So any big change is a very, very scary thing when that page is driving billions of dollars in revenue. So it makes sense that Amazon only makes small changes to their product page design.

Amazon’s design is often held up as a gold standard in e-commerce, but at some point we have to realize that maybe the emperor has no clothes – and we need to start calling it out so clients can stop asking us to “just make it like Amazon”.
